How _should_ this be done? In terms of "best practice".
<?php
function foobar ()
{
return new SomeObject;
}
?>
Or:
<?php
function barfoo ()
{
$tempvar = new SomeObject;
return $tempvar
}
?>
Please don't reply if you really, really don't know what you are talking

I'd choose this way:
function &foo()
{
return new Object;

I'm not exactly sure what your looking for, this is like asking
what is better:
$a = 'foo';
echo $a;
or
echo 'foo';
if tou want my opinion it should be written like this:
<?php
/*
* Create an instance of SomeObject
*/
function foobar() {
return new SomeObject;
}

What kind of requirement is this? Anyone can reply your email and
they will do so if they feel like it.

Thanks to everyone who's replied... appears to be quite a tricky one!!
$text = preg_replace('/<!--.*-->/su','',$text);
Did not work (was too greedy, matched multiple comments)
$text = preg_replace('/<!--.*?-->/','',$text);
Did not work (needed multiple lines)
$text = preg_replace('/<!--.*?-->/su','',$text);
Does work so far, finger's crossed.
Thanks again to John, Paul, Rob, Tom, et al.

Just for the record, it should be a capital 'U' for ungreedy. Lowercase
'u' is something else. :)

=======================================
This message is for the benefit of new
subscribers and those new to PHP. Please
feel free to add more points and send to the
list.
=======================================
1. If you have any queries/problems about PHP
try http://www.php.net/manual/en first. You
can download a copy and use it offline also.
Please also try
http://www.php.net/manual/faq.php
for answers to frequently answered questions
about PHP (added by Christophe Chisogne).
2. Try http://www.google.com next. Searching
for "php YOUR QUERY" may fetch you relevant
information within the first 10 results.
3. There is a searchable archive of the
mailing list discussion at
http://phparch.com/mailinglists. Many of the
common topics are discussed repeatedly, and
you may get answer to your query from the
earlier discussions.
For example: One of the repeatedly discussed
question in the list is "Best PHP editor".
Everyone has his/her favourite editor.
You can get all the opinions by going through
the list archives. If you want a chosen list
try this link :
http://phpeditors.linuxbackup.co.uk/
(contributed by Christophe Chisogne).
4. Not sure if PHP is working or you want
find out what extensions are available to
you?
Just put the following code into a file with
a .php extension and access it through your
webserver:
<?php
phpinfo();
?>
If PHP is installed you will see a page with
a lot of information on it. If PHP is not
installed (or not working correctly) your
browser will try to download the file.
(contributed by Teren and reworded by Chris W
Parker)
5. If you are stuck with a script and do not
understand what is wrong, instead of posting
the whole script, try doing some research
yourself. One useful trick is to print
the variable/sql query using print or echo
command and check whether you get what you
expected.
After diagnosing the problem, send the
details of your efforts (following steps 1,
2 & 3) and ask for help.
6. PHP is a server side scripting language.
Whatever processing PHP does takes place
BEFORE the output reaches the client.
Therefore, it is not possible to access
users' computer related information (OS,
screen size etc) using PHP. Nor can you
modify any the user side settings. You need
to go for JavaScript and ask the question in
a JavaScript list.
On the other hand, you can access the
information that is SENT by the user's
browser when a client requests a page from
your server. You can find details about
browser, OS etc as reported by
this request. - contributed by Wouter van
Vliet and reworded by Chris W Parker.
7. Provide a clear descriptive subject line.
Avoid general subjects like "Help!!", "A
Question" etc. Especially avoid blank
subjects.
8. When you want to start a new topic, open a
new mail composer and enter the mailing list
address [EMAIL PROTECTED] instead of
replying to an existing thread and replacing
the subject and body with your message.
9. It's always a good idea to post back to
the list once you've solved your problem.
People usually add [SOLVED] to the subject
line of their email when posting solutions.
By posting your solution you're helping the
next person with the same question.
[contribued by Chris W Parker]
10. Ask smart questions
http://catb.org/~esr/faqs/smart-questions.html
[contributed by Jay Blanchard)
11. Do not send your email to the list with
attachments. If you don't have a place to
upload your code, try the many pastebin
websites (such as www.pastebin.com).

Hope you have a good time programming with

David and all,
I apologize for not posting properly. I did not realize that headers were
keeping track of the threads of this mailing list. I will make sure I don't
do it again.
I am actually simply using the Host header to make a dynamic path to its
data location in my apache module.
Unfortunately, the mod_php4 modules is rather cryptic in how it does
things, and it looks like it doesn't do any of the variable setups on a
per-request basis, so it would be difficult to track where it puts that
information, but I guess its the only place for me to look unless you or
anyone else has a better idea of where I can tap in to make those kind of
changes on the fly...
In case no one else got my message due to my fopaux, I have included a copy
of my original message below.
To clarify, the goal is to set up some security variables like open_basedir...
Thanks,
Tim.
Hi all,
ok, I am writing an apache module that dynamically figures out virtual host
variables for data locations for my users.
I need to be able to set the php_admin_values for each request so that
those values get passed through to php and take effect for each request.
Normally, this would be static inside the apache conf file using the
php_admin_value directive.
Does anyone here know how I could set these variables dynamically ? Do I
have to load the apache configuration tables and change it manually ? or
can I set a particular environment variable that gets read by php ?
Thanks,
Tim.

Hi there, I am trying to upgrade my db class, so I can tell if what table
type of the table being queried is. More specifically i need to work out if
the table is an innodb transaction table, if so I would like to start the
transaction and commit and rollback when needed.
Let me know.

I already use and am happy with a variety of text editors (vim, emacs,
ultraedit, jedit, Homesite) depending on my needs, but I would like
recommendations for a PHP specific IDE that will run on Windows XP.
Specifically I am looking for something that can help with debugging,
provides efficient code browsing (functions, objects, etc) across multiple
files in a project, easy browsing through proper mappings to a development
server/local server, and hooks to PHP reference/help/website.
Needless to say, standard features like syntax highlighting, block
formatting, etc. are a requirement.
I've been looking at Zend Studio and Nusphere PHPEd as primary candidates.
However, I have a short window to buy something (fiscal year issues) so any
comments on these two editors (separately or in comparison to one another)
or other tools I should be looking at would be greatly appreciated!

Sounds like you just described Zend Studio perfectly. I used to use
the NuSphere PHPEd a few years back and quite frankly it was bugged to
hell - they have sorted out loads of those issues since then, but I
moved onto Zend Studio a year ago and won't ever look back. I have
been beta testing the 3.5.0 release for a while now and it's
absolutely great. The debugger is smart, the Code Profiler essential,
the code analyser is good too and the Project settings can span
whatever you need it to. I honestly couldn't code without it now.

The differences between the versions:

It does have a splash screen that asks if you want to buy a copy even though
its free.
Hope this helps

Hey, I was wondering if anyone knows of any easy ways to detect for HTML
input. I have a textarea box that I want users to be able to input either
plain text or HTML code. I will later display this input data, so if the
user input plain text then I will replace newline characters (\r\n, \n, \r)
with <br> tags, but if they input HTML code I don't want to format it before
displaying it. Basically is there an easy way to detect HTML code in
inputs? If you have any suggestions, please let me know.
Thanks,
Matt

Just one way of doing this, but...
$userinput = 'blah blah <b>bold!</b> blah';
$test_html = strip_tags($userinput);
if ($userinput !== $test_html)
{
echo 'They included html!';
}
else
{
echo 'Plain text';
}

To recap...
We have two servers:
1. USA - holds most of our databases, and E-mail. but specifically, the
usernames and passwords, or all our users (Lotus Domino Server)
2. UK - Runs our website. (Unix Server)
We wanted to be able to allow people to login on on server 1, and getr
authenticated etc, and then get redirected to server 2.
Using http_referer we would confirm that they came from server 1
However, as I discovered, that is not possible.
So what we did was this:
On the login form on server 1, the referering URL to server 2, contains a
varibale called 'secure'
we asign that variable that value of '4654376534' and divide it by the day
(eg: if it's the 12th of may, we divide by 12.. 7th of June, we divide by
7)
I know that this is crackable, but it's just a stop gap measure...
My problem today is this:
It's not confirming the values?
See my code below....
================
session_start();
$today_day = date("d");
$code1 = ($today_day+1) * $secure;
$code2 = $today_day * $secure;
$code3 = ($today_day-1) * $secure;
$master_code = 4654376534;
if (($code1 == $master_code) || ($code2 == $master_code) || ($code3 ==
$master_code)) {
$_SESSION[logged] = 'true';
$login_info = "You are now <b>Logged in</b>";
} else if ($_SESSION[logged] == 'true') {
$login_info = "You are still <b>Logged in</b>";
}
=================
I start by getting the date $today_day
As we're in two time zones, I don't wanna get caught out by the time
difference, so I've created a +/- 1 each side ($code1-3)
and fianlly, asigned the master input variable (the decoder)
Now it all works great..! (all variables echo what they should) however,
I'm not getting logged in?
I'm really stumped...
any ideas?
Tris...

What about allowing your UK server to access the database of your USA
Server? You could open a port to that specific IP address only, ...
Then authenticating users on the UK server would work like a charm.
You could even create a 'shared' database for basic session
information.
I think if sessions are used the overhead would not be overly serious
except for the one time a user has to log in.
Ok, I have no idea whatsoever about how to access a Domino Server, but
there just has to be a way... XMLRPC?
just a thought ...

I looked into getting PHP to talk to a Lotus notes database, and was
really really scared..!
I think this is my best bet, for now at least... however, my simple code
does not work?
Wierd...

... which does not lend easily to such comparisons.
If you're still intent on using this *ahem* 'security' scheme then I suggest
you use multiplication instead (just make sure that the largest number you're
processing is less than 2147483648 - or use the BCMath functions).

Hi,
i'm currently designing a website in which i have some forms with data saved in
database.
My customer wants that when he add or modify some datas in these forms, changes
will be made immediately in database. I really don't know how to do it and don't
know if it is possible.
Is there anyone who have fijnd a solution to solve that problem and who can help
me. I accept solutions in other langages than PHP like JAVA + XML.
thanks,
Marc

PHP cannot because it is server side and the action needs to send data
from the client to the server. You might be able to use JavaScript and
have the data updated as each field loses focus. Seems rather
inefficient.

To do this reliably, you'll need something like a Java applet. In your shoes,
I'd ask the customer how important this requirement REALLY is. It will cost
more to develop, and will increase the load on the database a LOT.

Hi List,
$string = "This is a test string to <title>SHOW ONLY THIS BIT</title> of the
string";
I have tried strpos, str_replace and other string manipulation things but I
cant get my head around how to achieve showing the text with the
<title></title> tags of the string.
Any help is appreciated and I thank you in advance for any help given.
Thank you

I guess the easiest way to do this would be to use a regular
expression:
if (preg_match("/<title>(.*)<\/title>/i", $string, $m)) {
$found = $m[1];
}
echo $found;

$b = strpos($str,'<title>')+7;
$l = strpos($str,'</title>') - $b;
$m = substr($str,$b,$l);
Sure, you can use regular expressions, but there's not really a need
unless this gets more complex. Even though you're executing more code
with this solution, it'll be faster than preg_match() (go ahead and
benchmark it).

Hi all,
I'm on a shared server, and I do not believe that I have access to the /tmp
directory where the session files are stored (I believe that is how it works
:). I want to keep track of which sessions are active. Basically, I just
want a list of the active sessions for my site.
How can I do this?
Thanks!

Hi
Are we talking about smb shares for linux.
If so, why dont you just ask your admin to create a share to "/tmp"
or create via php a web page that looks at /tmp and displayes the file.
Remember, there are many ways to skin a cat.
>Copied and pasted from za.php.net<
<?php
$dir = "/tmp/";
// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
echo "filename: $file : filetype: " . filetype($dir . $file) .
"\n";
}
closedir($dh);
}
}
?>
Kind Regards

Of course you have access to it. The webserver needs to be able to READ the
session files that it writes and hence you're also able to access those files
with PHP.

You would have to define what /you/ mean by an active session.
> How can I do this?
i) There is no way to determine which session files are for your site without
actually examining their contents.
ii) PHP does not store any site identification info in the session files.
iii) Hence you need to store a (hopefully) unique string in all your sessions
then search for this string in the session files.

You have the option of using session_save_path() and using a directory of
your own to store the session files. Then the "active" session count is just
a count of how many files exist in that directory. You have to implement
your own garbage cleanup of the session files, though.

If you use a database as container for your session data you could easily do
a SELECT COUNT(*) FROM sessions to get the number of the sessions. Using a
DB as session container is also more secure on a shared server (at least
that's what I often read about session security).
