Re: [PHP] how call a variable in a text
I don't think it is about readability:
$arr[3] = 'test';
$test = 3;
//This prints "$test"
echo "This doesn't work: $$arr[3]";
//This prints 3
echo "This works: ${$arr[3]}";
Using the same type way as before in this thread.
Above example is a classic one where readability and maintainability deal well
together.
First of all everything works as expected but obviously you need to know what
you need.
It is ambiguous to write $$arr[3] ... what do you expect?]
No I don't think it is. It produces "$test" and if this is what you need
echo it works nice :-) .
Did you mean the variable derived by $arr[3]?
echo "This works: {$$arr[3]}";
since curly brackets make the meaning of the expression explicit, it will be 3
indeed.
What is the less ambiguous, readable, easy to maintain, way to obtain that
result?
echo "This works: {${$arr[3]}}";
If our aim is to get the variable with name equal to the value of $arr[3]
Can you see now why I am talking about good practice? Zero ambiguity, and
that's how I like to code
Regards
Although I totally agree with the way of thinking and it is my style as
well.
But I though that the point of the thread was to present ways of putting
vars inside strings...

that has almost the same meaning of
$_ = '_POST';
echo count($$_);
which again, for readability brackets are suggested to improve
maintainability
$_ = '_POST';
echo count(${$_});

My point is that in the curly braces you protect the way the evaluation
is going to be made into the string. So you can put them anywhere as
long as it is meaningful.
See some examples:
http://php.net/manual/en/language.types.string.php
in the complex (curly) syntax section.

Re: [PHP] how call a variable in a text
Erm, the braces are meant to go *around* the variable, not around a
bit of it:
print "Test: {$var[0][0]}";
Thanks,
Ash
http://www.ashleysheridan.co.uk
In many cases braces can go around the variable name not the necessarily
around the whole variable (like the bash scripts). Those are coming from
the manual:
function test() {
// NULL -- not what initially expected
$string = '_POST';
var_dump(${$string});
// Works as expected
var_dump(${'_POST'});
// Works as expected
global ${$string};
var_dump(${$string});
}
So no they are not meant to go around. You can use them this way as well.

Yeah, I just forgot that PHP will correctly work with an array to a
depth of 1 inside of a string. Much like the above advice, I'd taken to
always using {} for arrays inside of strings, although not for strings
inside of strings unless I needed non-white-space text to immediately
follow said string. Would make more sense if I used the braces for
everything, but nobody has ever accused me of making too much sense
before!
Thanks,

This will also work (shell like style):
print "Test: ${var[0]}";
but this won't based on the same principle you mention above:
print "Test: ${var[0][0]}";

Re: [PHP] Please don't kick me!
Hi all. I know this question has been asked a thousand times on the list, but my searches in the archives are not being nice to me. So... please don't kick me. Currently, we use DOMPDF to generate PDFs from HTML. However, it's no longer maintained and it has a few bugs that we just can no longer live with. What PDF generating software do you use? It does not have to be free, but it must run on linux and may be command line or run through code. Some of the ones I have researched are... html2pdf html2ps html2fpdf xhtml2pdf fpdf tcpdf You're thoughts would be appreciated. Oh, my preference would be to send HTML/CSS to a script and it just automagically convert to PS/PDF. Thanks, ~Philip I find tcpdf very useful although ezpdf seems faster after a first look. I am using tcpdf though because it has a native utf-8 support that most pdf classes don't and that is vital to me. I wasn't able to print greek for example with some other classes I 've tried.

Assuming you have a unix-like OS and the timezone you mention is set to
the system clock I will have to guess that PHP uses different zone from
the system.
Try setting the date.timezone setting in your php.ini and see what
happens (don't forget to restart the web server to make changes take
effect) or use the ini_set().

Just a side question about your function.
Is there a PDO::FETCH_OBJECT that could be used in place of the
PDO::FETCH_ASSOC that you show.
If so, could you shorten that by one line by doing this
return $dbh->query($sql)->fetch(PDO::FETCH_OBJECT)->date;
Thanks Jim !! That is a very good suggestion.

// Instantiate a workbook

// Create a worksheet in the workbook
$worksheet =& $workbook->addWorksheet('Test');
// Set input encoding
$worksheet->setInputEncoding('UTF-8');
// Set protection for the worksheet
$worksheet->protect("");
// Create the formats format
$format_locked =& $workbook->addFormat();
$format_locked->setBold();
$format_locked->setHAlign('center');
$format_locked->setFgColor('yellow');

$worksheet->writeString(0, 1, "Unocked", $format_unlocked);

This protects the file with a blank password. I don't know if this is
the proper way to do this but it has been tested and works.

[PHP] Parse ini file problem
I am trying to parse an ini conf file using parse_ini_file but fails without returning something. I found this which is probably the reason: http://bugs.php.net/bug.php?id=44544 (the $ in the values) The problem is that this file has more than 7500 lines so it's kind of difficult to use quotes in all fields and there are several other reasons that I want to avoid quoting the values. In addition to that PHP 5.3 (which fixes this) is not stable yet and thus I can't install it in a production machine. So does anybody know any workarounds?? -- Thodoris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] fileinfo on RHEL5
fileinfo.so is, indeed, in /usr/lib/php/modules. But I know it's enabled, in any case. So, anyone know if this extension doesn't work well with 5.1.6? Well you could enable the error messages to see what is going wrong. The $type var is probably empty because the instantiation of the $fi object fails for some reason. -- Thodoris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thodoris wrote: Is fileinfo pecl extension installed as a package or with pecl? In case it is installed as an rpm try to remove it and install it as an extension in case the package is broken for some reason. I installed it with PECL: /usr/share/pear/bin/pecl install fileinfo Other question: where does PECL install this? It's not under /usr/share/pear AFAIK. This is the same as with the dev box, so I don't think it's an issue; I'm just curious. Pear and pecl are different. Pear is used to install pure PHP-coded extensions that you can include in your projects. You can use this piece of code that pear provides by just copying it somewhere and including it though not recommended IMHO. Pecl on the other hand provides C-coded extensions that you need to compile and may provide for eg APIs for known libraries that must exist in your system. That is what pecl command does downloads, compiles and installs the extension. A wild guess is that your modules probably live under the /usr/lib/php/modules directory or in a directory under the /usr/lib/php. Anyway, as I said, phpinfo() tells me it's installed & enabled. Have in mind that you will need the magic_open library for this to work. You mean libmagic? I have file-4.17-15.el5_3.1, which provides libmagic, installed. Strangely, for Fedora, it comes in the file-libs package. But I know that, for the dev box, I had to install file-devel to get this all working. Neither of these appear to be available for RHEL, which I'm discovering is a bit "interesting" to deal with, package-wise. The file package also provides /usr/share/file/magic*, which I have. I'd created a link to /etc/magic.mime but decided in the end to just pass the correct path to finfo(). -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Sending SMS through website
Hi All, Does anyone know how to send sms through a php website. I am completely new to the requirement and don't know even the pre-requisite of doing it. You can also drop in link to a good tutorial. Any help will be highly appreciated. Thanks and Regards, Dheeraj Bansal Never implemented something similar but I will share what I know. If you manage to set up an SMS gateway it will probably provide you some means (like an API, a spool-like directory, database etc) to pass messages to it. You can probably use PHP 's capabilities to pass the sms to the gateway and use it this way to send the message to the subscriber. Generally speaking this is the plan. But you will need to have a working SMS gateway and walk through its aspects and details. I am not sure but I think there might be someone selling the service that you may pay to use it in your site. I am sure that someone more experienced than me will reply when the time is right. -- Thodoris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] fileinfo on RHEL5
RHEL5/PHP 5.1.6
I'm having some trouble getting the Fileinfo package working. It
installed fine, and phpinfo() says it's enabled. But it consistently
returns an empty string when getting the MIME of a file.
/usr/share/pear/bin/pecl install fileinfo
vi /etc/php.d/fileinfo.ini
extension=fileinfo.so
ln -s /usr/share/file/magic /etc/magic.mime
The code:
define('FINFO_PATH', '/usr/share/file/magic');
...
$fi = new finfo(FILEINFO_MIME, FINFO_PATH);
$type = $fi->file($file_path);
$type is always empty. And, yes, the path to the file is good.
This works fine on the dev box (PHP 5.2.6). Unfortunately, the
decision to use RHEL5 for production was out of my hands and I'm stuck
with this older version. At least, I'm thinking it might be due to
that. I didn't see anything in the manual about it, though.
I did come across a post[1] online about doing file conversions where
the guy mentions rolling an upgrade to 5.2.4 for RHEL5 but wasn't
specific as to whether it was necessary to get Fileinfo to work at
all. I might try using that upgrade but thought I'd do a sanity check
here first. Any other reason it'd be returning nothing?
[1]
http://bhuga.net/2008/07/setting-your-system-file-conversions-with-file-framework
Is fileinfo pecl extension installed as a package or with pecl? In case
it is installed as an rpm try to remove it and install it as an
extension in case the package is broken for some reason.
Have in mind that you will need the magic_open library for this to work.

Of course it's possible... but you're probably not going to get the
results you want since you're taking 3 dimensions and trying to push

colour, and a bar to pick the colour. The following will produce a
colour picker, but it won't look like what you expect:

Re: [PHP] irrational behavior

When the line - sort($category) is commented out, the output returns

this case)
The code below:

The same phenomenon happens in another application using the

I don't want to sort the category; that has been taken care of in the
query.
It just doesn't make sense that sorting would affect the count. :-(
Well a wild guess is this:
This function assigns new keys to the elements in /array/ . It will
remove any existing keys that may have been assigned, rather than just
reordering the keys

take a LOT of memory, and it will take a while to download to the client, AND it
is 4096 pixels square! That's a fair bit bigger than most screens...

I assume that this running by the web server (/var/www/html) so a wild
guess is that the user that your web server uses to run (usually apache
or www) cannot access the Desktop directory. In order to use the suexec
feature you need to configure it or else the web server user needs to
have read/write rights to the directory you need to access like the
Desktop.
Though this not recommended. You could always run this script from
command line being root or whatever user is the owner of the Desktop
directory. Read this if you are not aware of how this can be done:
http://www.php.net/features.commandline
If the OP's system is set up properly, then nobody but root should be able to
read ANY of root's home directory, so the files will not be found.
For a start, one doesn't want config files in anyone's home directory if they
are for a system-wide server.
There is always suexec so this is partly true.
And one doesn't EVER want to have anything in /root that anyone but root needs
to access.
Couldn't agree more.
And one shouldn't be logged in as root unless one is doing a short-lived system
maintenance task: certainly one should not doing development work there...
This is the principle but handling files at root directory might be a
maintenance task and since PHP is a scripting language it can be used
for this kind of tasks mainly running from command line.
I know it sounds dictatorial, but it's (part-way to) best practice...
Those config files should be in something like /etc/apache/extra, perhaps, if
they are not safe in the web root (which they probably are not, unless the web
server is configured to keep them safe)
The OP could always use one of the already developed file browsers in
PHP. Never tried one besides webmin but a little googling could end up
very resourceful.

Re: [PHP] Re: Mail subject encoding breaks

Is it possible that sendmail (which is the underlying tool) breaks the mail encoding? I am not sure what you mean by breaking the mail encoding. I use the MIME message class and it works perfectly with any encoding, even multibyte character sets. Take a look at the examples test_email_message and test_multibyte_message.php . http://www.phpclasses.org/mimemessage I am not sure what is happening exactly but I think that for some reason the subject of the e-mail includes more than one encoding while using linux. The English part is encoded in ISO-8859-1 and the Greek part into something that I can't detect (probably because thunderbird doesn't support all encodings). The body of the message is UTF-8 as expected. I didn't try the suggested solution since I have solved this, but the original question was about phpmailer. I will give it a try however because it seems like a better solution and more robust than mail_utf8. -- Thodoris

Re: [PHP] bug or expected, mbstring.func_overload not changeable by .htaccess 5.2.8/5.2.9
Hello,
Besides the .htaccess which might be an apache configuration problem if
you use ini_set("mbstring.func_overload",2) in a script of this
directory does it work?
no, also the ini_set does not work for this Directive.
Sorry for the late reply.
The ini_set is meant to be used inside a php script not in an .htaccess
file.
So perhaps you could test this in a script specific manner.
In addition to this heck your apache configuration to see if you allow
.htaccess to be parsed.
apache and .htaccess are ok
i added a scond line which changes mbstring.encoding_translation from
off to on without problems:
Directive Local Value Master Value
mbstring.encoding_translation On Off
mbstring.func_overload 0 0
.htaccess:
php_value mbstring.func_overload 2
php_flag mbstring.encoding_translation On
IMHO this is not a good practice using .htaccess to alter php's behavior.
Perhaps you should consider ini_set after all.
Can you confirm or rebut this behavior?
Should we go to internals list?
Thanks,
Andre
Unfortunately I can confirm that.
This is a list with all the initial values you are allowed to change:
http://www.php.net/manual/en/ini.list.php
This is a script that shows all the mbstring extension values in an array:
";
print_r(ini_get_all('mbstring'));
?>
This array contains the default,local values and access level for each one.
Note that according to the manual:
http://www.php.net/ini_get_all
The access levels for every value are:|
Constant Value Meaning
PHP_INI_USER 1 Entry can be set in user scripts
PHP_INI_PERDIR2 Entry can be set in php.ini, .htaccess or
httpd.conf
PHP_INI_SYSTEM4 Entry can be set in php.ini or httpd.conf
PHP_INI_ALL 7 Entry can be set anywhere
|Although in the ini list the mbstring is supposed to have access level
2 I've noticed that I have access level 4 for mbstring.func_overload.
Perhaps *this is the problem*. You have access level 4 so that is why
you can't change the value using .htaccess.
I don't know if this is an expected behavior though. Can anyone else
confirm this??

Although greek are printed normally the characters are overlapping on
each other. The script in encoded in UTF-8.
Does anybody have any suggestions on this? Please any help would be
appreciated.

[PHP] fpdf adding font error
Hello gang, I know this is not an fpdf mailing list but if anyone has experience on the matter please help. I am working on a pdf generation part of a project and I am using fpdf to generate them. The content of the pdf needs to be in greek. But I am having difficulties to get the pdf generated properly. This means that I can't see the greek in the pdf file that is generated. I have tried to set the encoding to non-UTF since fpdf doesn't support UTF-8 but the problem still remains. As a second solution I am trying to add new fonts with the ISO-8859-7 encoding but it doesn't work as expected. The font is not being although I am following the fpdf's directions step-by-step. Does anybody know another way to generate pdf files with greek properly or can help me with the fpdf?? Thanks in advance. -- Thodoris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

That was what triggered this question. Templates are a black art to me. I don't even know where to begin to understand them. Every reference I have looked at so far assumes that I already understand the MVC pattern, which is also one of the dark arts. Let me put it simply. I can't grok OO. I tried to do OOP for several years, but it simply does not make any sense to me. As a direct result, I don't understand the concept nor application of patterns. So how do I figure out how to use templates without having to absorb those first? Can I learn enough this way to determine if a site can be converted from the current state (PHP and XHTML spaghetti) into templates and begin that transformation? Bob, You really would need to learn those concepts first OOP / MVC. There is a learning curve, but you really don't need OOP to be able to do an MVC style application, but it does make the code neater. One of the books that really helped me grok OOP is Head First OOP...another is Martin Fowlers Patterns of Enterprise Architecture. The MVC pattern is explained well in a number of places, but worth checking out are both the cakephp framework site and the codeingniter site. You'll find that there are people from both camps here, pure OOP and other just as happy with procedural coding styles. Many use both, using objects to handle common tasks like DB interaction or filesystem processes. Yes, I have to deal with both camps here as well. Of five developers doing PHP at the moment, two are primarily using OOP. But I spent 3.5 years as part of a team developing MS-Windows services in C++. After all that time, I was only able to write basic functions for others to convert into methods or classes. I could eventually find my way around in some of those classes, but it seemed that every time I figured out what was where, somebody "refactored" a major component and I had to start all over again. All I saw was a lot of unnecessary overhead and obfuscation which made little sense in the long run and slowed down both the development and the application. The result was a handful of DLLs that are shared between several products, and each time anything is changed in one of them, every product needs to be retested to make sure nothing got broke and some have to be recertified for PCI-DSS as well. So you are telling me that I can forget about trying to use templates. Since I can not understand OOP, there is no chance I will be able to use them. Just knowing that will probably save me several weeks of frustration. Thank you, Bob McConnell Well think of the positive side that you don't need to write in OOP in order to use Smarty. Think it just like a class used for displaying the output (simply put). At least I've been doing this for some time now (the non-OOP part). I have a feeling that someone coming from the procedural way of programming would have problems probably with the templates instead of the development part. -- Thodoris
Re: [PHP] Smarty Tips and Techniques
That looks nice, but how do I get to the point where I can understand how to use it? I have also looked at the Smarty site <http://www.smarty.net/>, but their documents assume significant experience in building and using templates. Where can I find guidance or tutorials on how to do all of this, starting with only a rudimentary knowledge of HTML and PHP. It would be best if they also focused on procedural rather than object oriented code.

Smarty is a template engine for PHP that you can use to separate data and logic from web design. This way programmers can work on the php scripts and designers can work on the templates for the same web site. Here is the link: http://www.jampmark.com/php-programming/16-very-useful-smarty-scripting- tips-and-techniques-to-make-templates-smarter.html Hope you find it useful. Virgil I have stared using smarty myself in a recent project I am still making and I'll have to say that it has its virtues. Look at a simple example in the smarty's site and use the manual for any questions. You will probably find some stuff by googling. The templates (simply put) are actually html-like that has some php variables inside you may assign before displaying the actual template. This way you customize the template to output what you need. Above that you may start using the statements to automatically build forms, tables etc I like the fact that there is a cache and that the templates get "compiled" which make them faster to process. Nevertheless you need time to get familiar with the smarty way of thinking as with all frameworks and template engines you need to use. -- Thodoris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] assign associative array values to variables?
I have been tearing out my hair to figure out a way to place array
values into $variables with not much luck. I can echo the array to the
screen but I can not manipulate the results.
I have searched wide and far all day on the web and I find nothing that
points the way how to extract values from an associative array and
assign them to a variable.
I expected to find some elegant way to do it. Here's the code that
outputs the values:
if ( isset( $book_categories[$bookID] ) ) {
foreach ( $book_categories[$bookID] AS $categoryID ) {
if ( isset( $category[$categoryID] ) ) {
echo($category[$categoryID]['category']);
}
}
}
this will echo something like "CivilizationGods And GoddessesHistorical
PeriodsSociology & Anthropology" (I have not added breaks beween the
categories as there is more manipulation needed on them)
This works for as many categories as needed. Manipulating each value
should not be a problem once it is in a string variable using switch and
preg_replace() as each category needs to be stripped of spaces, commas
and &s.
Perhaps extract() ??

You want it unbuffered so it doesn't get retrieved in mysql, send the whole result set to php then you can use it. You want to start using it immediately - so make it unbuffered. Either way if the result set is going to be large your MySQL's memory or PHP's memory may exceed. So if you use either you may need to fine-tune PHP by increasing the per process memory (memory_limit in php.ini) or MySQL.

Re: [PHP] function array problem
I've had a bit of a problem with a function I'm using for a form.
Essentially, the function looks like this:
function addEvent($values = Array('name' => '', 'venue' => '',
'description' => '', 'errors' => Array()))
{
// code here displays the form
}
The function is used to both display an empty form, and the form
populated with values again should there be any validation errors.
Now this works fine when the form has been filled out and there are
errors present, as I can call the function with the correct array
values. However, when I call the function with no arguments (intending
the function to populate the $values array itself) all it does is
present me with an empty array. A print_r($values) just returns
Array( ), no key values defined.
I altered the function to this:
function addEvent($values = Array())
{
if(count($values) == 0)
{
$values = Array('name' => '', 'venue' => '', 'description' =>
'', 'errors' => Array());
}
// code here displays the form
}
then all works as intended. Question is, am I being dense, or is there a
reason why this shouldn't work?
Ash
www.ashleysheridan.co.uk
While reading this thread I've noticed that you all use "venue" in the
index of the parameter array. Is this intended or you actually mean "value"?
You may want to consider these functions:
|func_get_args
||func_get_arg|
|func_num_args|
to make the functions input more loose and have it accept multiple
formats as needed like one dimensional, two dimensional or simple
parameters the same time.

Re: [PHP] PHP AS an FTP server
On Tue, 2009-02-17 at 18:54 +0200, Thodoris wrote: Hi, This is probably a bit stupid, but I've been having issues getting any of the good FTP servers running on my Ubuntu 6.06 (LTS) box. I've tried Pro-FTP, Pure-FTP, and briefly installed some others, but the versions available for my distro don't seem to support MySQL (or I'm simply doing something wrong). AFAIK in most distros the ftp servers come without mysql (or database) authentication support. If this is what is happening in your case you need to compile the ftp server from source adding a configuration time option to enable the database support. Anyway, I had the thought that the FTP server won't be used much, as I mainly use SSH, however I need to be able to give other people access, which is why I'm wondering if there are any PHP scripts that can be used AS an FTP server. That is, I'd setup Apache to accept on the standard FTP port(s), and get it to point everything to a PHP script, which I could then use to pull user/pass details each of which would have their own directories, allowing each user to access a sym-link to their domain(s) log file, website directory, and anything else. In case you have ssh enabled you may use the sftp subsystem that openssh supports if it fits your needs. It's more secure than plain ftp but you still have to add local user accounts which is a bad idea imo. You may use PHP to upload files using the http (and not the ftp) protocol by making a project that authenticates the user provides him the ability to upload, delete and download files using forms. There has to be something already written that implements such a procedure in case you don't want to code this by yourself. You may google to find whatever fits your needs. Has someone already got a script that does this (at least accepting FTP connections), or is this a crazy idea that's just not possible? Should I just compile the latest version of some FTP server, and try and configure that to do what I want instead? I suggest that since you need ftp access it would be much better if you could configure an ftp server instead of writing something on your own. The vsftp daemon is a good solution to your problem written including advanced security features but I don't know if it supports mysql authentication. On the other hand pro-ftpd does support modular authentication (mysql, ldap etc) if you compile the proper module. Thanks. -- Thodoris I used vsftp for several FTP systems at work, and bar a few problems (errors on my part!) they work just fine. I've even got PHP talking to various Bash scripts to manage users and permissions for the FTP, and, touch wood, everything works well. I wouldn't really agree that allowing local users to FTP in is a bad idea. I'm using just that method for my systems. The users, etc are only ever created through a web interface, which forces certain rules on usernames, which as far as I see it, is the only problem. As long as the vsftpd.conf file is configured correctly and securely, the whole thing will remain pretty tight. Ash www.ashleysheridan.co.uk The local users part was about ssh-sftp access Ash not ftp. IMO when you add local users you add extra risks to your system than simple ftp (non-local) users may not cause. Of course if you secure your system carefully everything will work fine but I would avoid that and there are many security issues that here is not the place to discuss. Of course if this fits your needs I have no objections. -- Thodoris
Re: [PHP] Opinions Please, Describing PHP as Web Framework of C and C++
What's so funny? Assembly is just a framework for microcode. Cheers, Rob. So, what is the level that actually polarizes the sectors on the hard drive? Anything more abstract then that is then an API right? I guess it abstracts a level but I can hardly say that microcode is actually a programming language and assembly as well. Since API is a Programming Interface it was to do with a programming language. So I have the feeling that the discretion is made on what it actually is a programming language. On the other hand the framework is usually use to describe an abstraction of the same language. That is why I don't feel right saying that PHP is actually a C framework. But probably I feel right saying Zend is a PHP framework. My problem I guess is not the abstraction itself which happens to exist in all software and hardware technology but what you abstract each time and what term you choose to use. An example that comes in mind is about networks. You can say that the http protocol is a framework of underlying tcp protocol although it is comes as an abstraction. -- Thodoris

Because the PHP code is not running (because of the syntax error), and thus not setting the error reporting as desired. You'll need to aither use a .htaccess file (if you're running Apache) or make the changes in your php.ini file (and restart your web server). Either way you won't be able to use the constants (which you use only in a PHP script.

So that you don't need to set it in every script during runtime as you mentioned. I would look at doing this only for a testing area, but not for a production area. If they are one in the same, then you could setup to different sub domains, one for testing and one for production. They can point to the same DOCUMENT_ROOT for that matter, just have different running configurations. Totally agree on that since Jim has a very good point. You shouldn't leave error reporting active in a production domain because it reveals a great deal of information about your code making you site vulnerable to attacks. I suggested that assuming it is a testing-development domain. The less someone knows about how things work the more secure your site becomes. -- Thodoris
Re: [PHP] Full versus relative URLs
for that matter, you could use variables to specify the relative path to make it absolute within each of the production and dev environments. Another possible solution I can think is building configuration files that could include the paths and parse them to find the path every time you need it. This conf files would be different between the two machines and you will only need to upload the source files without consideration since the directories will actually inside the conf files. A database table that would store the paths could always be an alternative that you could perhaps load into the session to avoid overhead. -- Thodoris
Re: [PHP] Full versus relative URLs
I know it's been said before, but beware of relying on this value just for the sole purpose of deciding where things are located, as without a bit of error checking on it, it can be used for injection attacks and what-not, although, sadly, I forget the exact post recently that had the link that explained this issue on PHP_SELF. Alternatively, $_SERVER['PHP_SELF']) could be switch()ed for known values, and $path be set accordingly with hardcoded values. Didn't notice this thread passing from the list. I will look into it. But sometimes you need to detect where something is located and that's the point of the whole conversation. If you hardcode the values then you need to change them while renaming or moving files and directories So what someone should do to accomplish such a behavior? Without being vulnerable to injection attacks of course. -- Thodoris

The script goes like this: #! /usr/local/bin/php The problem is that when I run the script I get this error: Script: './bcom.php' /usr/ports/lang/php5/work/php-5.2.8/main/main.c(2015) : Freeing 0x2871F2A8 (43 bytes), script=./bcom.php === Total 1 memory leaks detected === This is hosted on a FreeBSD 7 machine with: PHP 5.2.8 with Suhosin-Patch 0.9.6.3 (cli) Anyone knows what is happening ?? I have to mention that the array is printed as expected. -- Thodoris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] display_errors and error_reporting not enough?
When I make something wrong like syntax error; I get blank pages. Because the PHP code is not running (because of the syntax error), and thus not setting the error reporting as desired. You'll need to aither use a .htaccess file (if you're running Apache) or make the changes in your php.ini file (and restart your web server). Either way you won't be able to use the constants (which you use only in a PHP script. IIRC the correct directive would be: error_reporting 2047 In other words try to set: display_errors=On error_reporting = E_ALL in your php.ini which is: /etc/php5/apache2/php.ini As far as I can see from you phpinfo page. So that you don't need to set it in every script during runtime as you mentioned. -- Thodoris
Re: [PHP] PHP AS an FTP server
Hi, This is probably a bit stupid, but I've been having issues getting any of the good FTP servers running on my Ubuntu 6.06 (LTS) box. I've tried Pro-FTP, Pure-FTP, and briefly installed some others, but the versions available for my distro don't seem to support MySQL (or I'm simply doing something wrong). AFAIK in most distros the ftp servers come without mysql (or database) authentication support. If this is what is happening in your case you need to compile the ftp server from source adding a configuration time option to enable the database support. Anyway, I had the thought that the FTP server won't be used much, as I mainly use SSH, however I need to be able to give other people access, which is why I'm wondering if there are any PHP scripts that can be used AS an FTP server. That is, I'd setup Apache to accept on the standard FTP port(s), and get it to point everything to a PHP script, which I could then use to pull user/pass details each of which would have their own directories, allowing each user to access a sym-link to their domain(s) log file, website directory, and anything else. In case you have ssh enabled you may use the sftp subsystem that openssh supports if it fits your needs. It's more secure than plain ftp but you still have to add local user accounts which is a bad idea imo. You may use PHP to upload files using the http (and not the ftp) protocol by making a project that authenticates the user provides him the ability to upload, delete and download files using forms. There has to be something already written that implements such a procedure in case you don't want to code this by yourself. You may google to find whatever fits your needs. Has someone already got a script that does this (at least accepting FTP connections), or is this a crazy idea that's just not possible? Should I just compile the latest version of some FTP server, and try and configure that to do what I want instead? I suggest that since you need ftp access it would be much better if you could configure an ftp server instead of writing something on your own. The vsftp daemon is a good solution to your problem written including advanced security features but I don't know if it supports mysql authentication. On the other hand pro-ftpd does support modular authentication (mysql, ldap etc) if you compile the proper module.

Re: [PHP] Opinions Please, Describing PHP as Web Framework of C and C++
I didn't mention that it was a C specific framework, I just said IMO it was similar to a framework for the web. It's an opinion so I can't be "wrong". In my opinion earlier versions of PHP *could* (not should but could) be described as a framework in essence, however I wouldn't say that anymore since it has evolved so much. In your opinion I may be completely wrong but that's the idea of an opinion. I think that this is what you said: I prefer calling PHP as Web Framework of C and C++ Btw opinions and personal styles are always welcome. Besides, if you cross reference your description of a framework: "basically because when you use a framework (or API or whatever label you choose to use for describing it) in a language it just abstracts some aspects of the language making it "easier" to code". That's my point meaning that PHP is not exactly abstracting C as other frameworks happen to abstract PHP. With the description of the original PHP: "It had Perl-like variables, automatic interpretation of form variables and HTML embedded syntax. The syntax itself was similar to that of Perl, albeit much more limited, simple, and somewhat inconsistent." That of course was PHP and you probably have a point. Then surely what is described is just a way of abstracting parts of the language to make it "easier" to code.

Re: [PHP] Apache odd behavior
I'm submitting a url like this: http://mysite.com/index.php/alfa/bravo/charlie/delta The index.php calls has code to decode the url segments (alfa/bravo/charlie/delta). It determines that the controller is alfa, the method is bravo, and converts charlie and delta to $_GET['charlie'] = 'delta'. It verifies that the controller and method exist, and calls the controller and method. This works fine. The right controller gets called and the right method, and the GET parameter looks like it should. The method sets some variables and then calls a render() function to render the page, which is in the doc root of the site. The page does get rendered, but without the stylesheet, and none of the graphics show up. Why? Because, according to the logs, Apache appears to be looking for the images and everything else in the directory index.php/alfa/bravo/charlie/delta, which of course doesn't exist. No, I don't have an .htaccess file with RewriteEngine on. Apache figures out that index.php is the file to look for in the original URL, but can't figure out that everything else is relative to that file, not the entire URL. This method is in use in at least one other MVC framework. What am I doing wrong? Paul I assume that in order for this to work you will have to use mod_rewrite for apache to work properly.

Re: [PHP] Opinions Please, Describing PHP as Web Framework of C and C++
Hello list. Recently we had some serious discussion on local boards. I prefer calling PHP as Web Framework of C and C++ if you had a time for this fruitless discussion. Please send your opinions. Regards Sancar I think that you can't assume that PHP is a C framework for the web, basically because when you use a framework (or API or whatever label you choose to use for describing it) in a language it just abstracts some aspects of the language making it "easier" to code. Since you can't compile PHP (as you would probably need to do with a C API) and since you don't even need C to write something in PHP you can't call it a C or C++ framework. In addition to this there is an API for C that can be used to code web applications and it is known as CGI (it is provided by many languages) PHP is coded in C and some things are similar in syntax and style but this is the only relation I can find between the two. -- Thodoris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I tried to make some with dns_get_record and gethostbyaddr, but couldn't make anything Thank Daniel Well actually you can't basically because of the way the Name Service reverse resolution works. AFAIK you may assign many domain names to a single IP as A records (main resolution option) or as CNAME (aliases) but you can't assign multiple IP's on the same domain name (meaning you can't make many PTR records for the same IP). So perhaps there are solutions to this using search engines but you can't know for sure.

Re: [PHP] PHP OOP
Hi gang: At the college where I teach, they are considering teaching OOP, but they don't want to settle on a specific language. My thoughts are it's difficult to teach OOP without a language -- while the general concepts of OOP are interesting, people need to see how concepts are applied to understand how they work -- thus I think a specific language is required I lean toward C++ because I wrote in it for a few years AND C++ appears to be the most common, widespread, and popular OOP language. However, while I don't know PHP OOP, I am open to considering it because of the proliferation of web based applications. My personal opinion is that's where all programming is headed anyway, but that's just my opinion. With that said, what's the differences and advantages/disadvantages between C++ and PHP OOP?

Re: [PHP] Boolean Assignment Operator
2009/2/2 Gavin Hodge
Hi,
I'm fairly new to PHP, having migrated from the Java / C# world.
I wrote some code similar to the following:
$success = true;
$success &= operation1();
$success &= operation2();
if ($success === true) {
operation3(); // depends on 1 and 2 being successful
}
This didn't work as expected. After a bit of digging I found:
* The &= operation isn't mentioned anywhere in the PHP documentation
* The &= function seems to work as expected, however the following is
observed...
$success = true;
$success &= true;
print $success == true; // outputs 1
print $sucesss === true; // no output
* The 'or' assignment operator |= causes no errors but doesn't work.
Can any PHP gurus explain why the &= operator works at all, and why
=== seems to fail afterwards?
Cheers,
Gavin.
Hey,
never heard of the "|=" operator. So I think php does not support it.
Not true. This works just fine:
And gives 1 as expected.
I cannot say how "&=" works in Java or C# but as of php it works like that
(IMO) (reference instead of copy):
$var1 = "test1";
$var2 = $var1;
$var3 &= $var1;
$var1 = "test2";
echo var1; // "test2"
echo var2; // "test1"
echo var3; // "test2"
The manual does describe these as "combined operators" in the assignment
operators section. See the last example:

Re: [PHP] Clarity needed
Hi gang: I need some fog removed. I have a problem where I have an unlimited number of tutors teaching an unlimited number of courses. When I call upon a tutor, I want to see all the courses they teach. In my old days, I would just set up a linked list of courses and attach it to the tutor (another linked list). As a tutor adds courses, I would just add the course to the end of the linked list. If the tutor deletes a course, then I would remove it from the list by changing a single pointer. If I needed a list of all the courses the tutor taught, I would just run down the linked list pulling them out as needed. But now I have to think in terms of records in a database. I'll eventually figure it out, but what are your suggestions/solutions? I understand that I can have one record set up for each tutor, and another record set up for each course, and then tie the two together by another record like an assignment. That way I can have as many assignments as I want tying courses to tutors. It that the way you guys would do it? Thanks, tedd There is a very good schema for doing thing like that in this pdf.

Re: [PHP] kadm5 Library
Sorry, I could have been a little clearer: I can't recompile PHP. It's against our general policy to use custom compiled software on the grounds that there are too many sysadmins managing a lot of these machines and if some software is custom compiled and others not, it gets too confusing when it comes to keeping the machines updated and patched. We're talking a dozen sysadmins and hundreds of machines here. :) That is understandable. No harm is done and sorry for the late reply. I did try to compile the PECL library by specifying the path to the Kerberos libraries as you suggested, but it turns out that the normal version of Kerberos seems to have, among other things, a "krb5/admin.h" header file, and the one that comes with CentOS has "krb5/krb5.h" instead, and even when I change the source code to use "krb5/krb5.h", it still throws about 50 errors talking about missing functions and re-defined functions and so on. Did you try to install krb5-devel. Try "yum search krb5" to see all the available packages that CentOS includes. In case your yum doesn't find something you may add more repos like Dag's: http://dag.wieers.com/ It is just an rpm that updates the systems repositories that I find very useful. I'm thinking that the problem is that the PECL module was designed to work with one version of the Kerberos library and CentOS provides a different version. I guess I was really asking if anyone had any diffs or anything I could apply to the PECL module to make it compile on a CentOS machine. Or perhaps is there a Yum repository somewhere that I could use to get a version of the PECL module precompiled for CentOS? I am not aware if there is a pre-compiled package for kerberos but Dag's repo doesn't provide it AFAIK. It does provide some other pecl extensions like php-pecl-fileinfo etc but not this one. What you need is to find a kerberos rpm to include development header in order to compile it your self. I should point out that the Perl Kerberos module did install and compile successfully on this machine, so I'm fairly sure that Kerberos is itself working.

[/snip] CGI is a gateway to be used by languages PHP is a language First of all try not to top post this is what we usually do here. Well CGI is a standard protocol implemented by many programming languages. You may start googling to find about it but this is a start: http://en.wikipedia.org/wiki/Common_Gateway_Interface Both Perl and PHP can work with CGI but working with Perl-CGI is not something that we should discuss in this list since this is a *PHP* list. IMHO you should start reading some aspects of web development to make some things clear before start asking questions in the lsit. This will improve your understanding and it help us to make suggestions. -- Thodoris
Re: [PHP] Email configuration
2009/2/5 It flance : Hi all, I've installed php and mysql in fedora. Now i am able to create php programs. But when I am unable to use email in my programs. I am wondering what is the easiest way to use email in my php programs. Can i send email from my personal computer. I am a regular person connected to internet through an internet provider. Is there any preconfigured software or I have to go through the configuration of sendmail for example? Thank you Sorry... But I need a _little_ bit more information. What operating system do you use? Linux/Windows/Mac/other? The main problem is that most of the big email providers don't accept mails from dialup connections, but there are solutions to work around this. For now start by telling me which operating system you have. I think that the OP mentioned the word fedora somewhere above... To the point: Your linux probably has already installed the sendmail suite. If that is the case (run rpm -qa | grep sendmail to check) you may safely use the PHP's mail function for simple things. In case you don't have sendmail installed use: # yum install sendmail http://www.php.net/manual/en/function.mail.php If you need more advanced features like for e.g. adding attachments to your e-mails you may consider other options like phpmailer. I have never used it myself but many people that belong in this gang are very fond of it. http://phpmailer.codeworxtech.com/ Keep in mind that in case you have compiled PHP from source without having the sendmail installed you may need to recompile it. You can find this by making a phpinfo somewhere. In case you have installed from package no harm is done. Put this in a script: You will find "sendmail_path" somethere in the resulting page or something like that "Path to sendmail". If this is set then everything will work like a charm. -- Thodoris
Re: [PHP] function_exists question
Is there a way to check not only if a function exists, but also to check that the number and types of parameters desired match a function definition? The reason being that additional options have been added in php 4 and 5 to various standard function calls, but I'm still running a php3 and php4 server in addition to a php5 server. I would like to make sure that certain "extended" function calls still work in all versions (or I'll perform the tasks "manually", albeit less efficiently). One example I can think of is the round() function. The $precision parameter was added in php4, so will not work in php3. However, function_exists would return TRUE for both 3 and 4, but round itself would fail if I tried to send a precision level to the php3 server. Thanks much, Matt P.S. Of course the modified "function_exists" would unfortunately have to be a recognized function/method in php3 in order for me to call it to check parameter counts on a php3 server :( I am sure you have some good reasons for keeping php3 right? Why don't you consider updating to at least php4 ?? PHPv3 is not even maintained and PHPv4 is not being developed any more. So by the end of this year (I hope) we will start using a stable PHPv6. IMHO you should consider changing your code (if this is possible) to a more mainstream version. -- Thodoris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Sometime the code works and sometimes doesn't
Hi,
Here is a code for PHP password sending. There is some strange thing
happening. This code DOES WORK but not always. So I might be able to get the
password in my mailbox once but not always. What could be wrong.
$host = 'xxx';
$user = 'xxx';
$password = 'xxx';
$dbName = 'xxx';
// connect and select the database
$conn = mysql_connect($host, $user, $password) or
die(mysql_error());
$db = mysql_select_db($dbName, $conn) or die(mysql_error());
// value sent from form
$emailAddress=$_POST['emailAddress'];
$sql="SELECT password FROM mytable WHERE emailAddress='$emailAddress'";
$result=mysql_query($sql);
BTW I think that this vulnerable to SQL injection.
So don't put this piece of code in a real as is. Instead escape before
making the query with mysql_escape_string:
http://www.php.net/manual/en/function.mysql-escape-string.php
// keep value in variable name "$count"
$count=mysql_num_rows($result);
// compare if $count =1 row
if($count==1){
$rows=mysql_fetch_array($result);
// keep password in $your_password
$your_password=$rows['password'];
$subject="Your password is retrieved";
$header="from: Great Site";
$messages= "Hi \n\n Your password for login to our website is
retrieved.\n\n";
$messages.="Your password is '$your_password' \n\n";
$messages.="You can use this password";
// send email
$sentmail = mail($emailAddress, $subject, $messages, $header);
}
// else if $count not equal 1
else {
echo "Not found your email in our database";
}
// if your email succesfully sent
if($sentmail){
echo "Your Password Has Been Sent To Your Email Address.";
}
else {
echo "Cannot send password to your e-mail address";
}
?>
There must be something that I am doing wrong. Otherwise I could have always
gotten the password in my mailbox. Please help.
Thanks in advance,
Chris

Re: [PHP] php rpm
Daniel Brown wrote: On Wed, Feb 4, 2009 at 09:46, wrote: Okay here is my question. Does anyone know of an RPM of php that is pre-compiled with all the extras like soap, mssql, freetds, etc... Afternoon, Rich, et al; On an RHEL 5.3 system, you should already have 'yum' installed with the repos ready to go by default, so just drop to a command line and, as root, type: yum install php-soap yum install php-mssql yum install php-pdo etc. If your 'yum' isn't working from the get-go, check http://rpmfind.net/ or http://pbone.net/ for the individual RPM's. This probably more then one rpm :-) . You can do most of things using your distro's repos but usually PHP doesn't come in a single rpm. The truth is IMHO that pre-compiled packages are responsible for some failures in certain circumstances but generally are very good if you don't want to get your hands dirty. A good way to see how is your distro giving you a prepackaged PHP set of rpms is using yum: # yum search php This is to get the list of all the available packages. You can then go and install what you need. Using: # yum install php (and whatever you need) It is not a good practice making an rpm with all the features included because it could become huge and it will probably need many dependencies in order to get installed properly. IMHO that is why the best OS to use as on a web server is FreeBSD because of the flexibility provided by the ports system and the way that PHP is divided into small parts that can be added or removed easily. Not to mention that you are compiling PHP (as a port) and you can update it or remove it like a package the same time. Again this is my point of view that I wanted to share. --- Thodoris

Re: RES: [PHP] calculate the time that day ends
Try:
echo date("H:i:s", mktime(23-date("H"), 59-date("i"), 59-date("s"));
This is I guess how much time we have to reach midnight. But the
question is how to calculate the time that sun stops showing its
refreshing light.
