Is this the case?
You would need to use mod_rewrite.
You might also be able to get this to work by changing the include_path
and creating a special "loader" script in their folder.
define('INCLUDE_PATH', '');
ini_set("include_path", INCLUDE_PATH);
That way the application includes would still work if you didn't specify
absolute paths...
I have a few scripts that use the include_path, and they look something
like:
That way I just have the initial call to set the include path, and I
don't have to worry about it anymore.

As for automatic CVS via PHP, it depends on your take on it...
Eclipse has a CVS piece to it which seems to work well (I've installed it,
but most of my stuff is layered and I don't have a reason for CVS), though
someone also posted about cruisecontrol on the sourceforge site.
What have you found and tried via a google search?
Wolf
Maybe look at Phing[1]? Skimming over the docs (I know you said you
use CVS) I saw a task you can define to check files out form SVN.
There might be a cvs one somewhere or you could extend it and write
your own.
[1] http://phing.info/
Another option would be to write your own. If your requirements are
super specific, then that might be the best route. I can't imagine it
would be too difficult.
You can use shell_exec to execute the CVS checkout, and any other CVS
command necessary. Don't forget to use escapeshellcmd() either:
http://us3.php.net/manual/en/function.escapeshellcmd.php
After it's checked out, then you can use shell_exec() again to run the
compile command. If it takes a long time, you might be best just
sending the command to the output so you can copy and paste and run it
yourself, or just make sure you set_time_limit(0), or some amount of
time it should finish compiling in.
I assume it's an internal app, so you wouldn't have to worry too much
about it looking pretty or any of the other time consuming operations.
$cmd = escapeshellcmd('/usr/bin/cvs -d :ext:[EMAIL PROTECTED]:/.../cvsroot
checkout module');
$output = shell_exec($cmd);
// do something with output if you need
$cmd = escapeshellcmd('/path/to/module/configure');
$output = shell_exec($cmd);
echo "done!";
?>
Something like that anyway. That's overly simplified of course, but it
should get you a start if you want to write it yourself.

You're probably going to have to code that sucker on your own and slide it in as a cron job on your build server to get the latest/greatest whenever needed. I haven't come across anything like it before, but I definitely like the concept. Wolf I had an idea to tie a ticket system with SVN. Each ticket would be associated to a change in the code. In the ticket system you put in the different revisions that were checked in for that ticket. Then when you go to "promote" the ticket for testing, it'll check and make sure that there were no conflicting changes and merge it if possible to the next branch. The details are a little fuzzy after a few months of not thinking about it. The XML output from SVN would come in quite handy at that point though. It would have been cool, but it would have been complicated. We didn't have the time to work on it. I think Trac is somewhat similar.

If you have ruled out web server and ssh, then you can use ftp using

FYI... If you're using yum I assume it's a Linux machine (maybe

and not Unix.
If you want to use rsync and scp in a cronjob (for continuous transfer
at a
predefined interval), you may need to set your server (read ssh) to
accept
connection without password.
Ref : http://linuxproblem.org/art_9.html
BUT If you really want to do that from PHP, you can install a web
server
and
enable http as your stream for opening files. (In php.ini)
You can read the file using fopen or any other file functions, then
can
write that file to the server on which script will be running, then you
can
set this script as your cron job.
For example :
$filecontents=file_get_contents("http://firstserver/file.txt";);
$fp=fopen("path to local file", "mode");
Now use $fiiecontents to write the file using $fp resource.
BUT remember, using rsync is always a better solution, and
file_get_contents
and file functions are resource hungry, specially they will consume
more
memory of your system.

Well I haven't ruled our webserver and ssh but I don't have much
options. Number 1 is that I have many such computers and I don't think I
can afford to install a webserver on all of them atleast. And coming to
SSH, I can't use it because of the scenario that I explained. Please let
me know if you have any other advice.
Thank You
I second the NFS mounting. You can share a directory somewhere on
computer A. Then computers B and C connect to it. That way with PHP
you just copy the file to the shares, and computers B and C
automatically see the file there. Outside of that FTP might work well
for you. Maybe even SCP, since you already have the keys on server A
(as long as you don't have a password when connecting to B or C). rsync
can work over SSH as well, and you could create a simple script to run
rsync as often as you need.
haha, I guess that's not exactly seconding NFS, more seconding not
transferring files over HTTP.

Thanks for the catch. I work from home and I hadn't had my coffee yet

I have been starting to use in_array more often as well. Far too many
times I'll have to go back and add more options later, then the IF
statement gets huge. Someday I'll kick the habit for good though.
Oh, it might also be a bit easier to store the acceptable extensions in
an array before the IF statement
$ext = $this->getFileExtension($file);
$acceptableExtensions = array('png', 'gif', 'jpg');
if ( in_array($ext, $acceptableExtensions) ) {
// do something

That way the conditional doesn't grow as more and more values get added.

Thanks, Dan Dan, I can tell you that depending on the size of your files is going to dictate the route you want to go. I have a CSV with 568,000+ lines with 19 different pieces to each line. The files are around 180M apiece and it takes my server about 2 seconds to run a system grep against the files. I can run a recursive call 7 times against a MySQL database with the same information and it takes it about 4 seconds. IF you have system call ability, a grep wouldn't be bad, otherwise I'd suggest loading the csv files into MySQL tables and checking them for the information, then dropping the tables when you get the next files. You can backup the databases such as a cron job overnight even. HTH, Wolf If you do go the MySQL route, MySQL can import CSV files natively, and it'll be a lot faster than doing it through PHP. Just look up the syntax for the LOAD DATA INFILE command... or look here. http://dev.mysql.com/doc/refman/5.1/en/load-data.html Here's an example: LOAD DATA LOCAL INFILE '/importfile.csv' INTO TABLE test_table FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' (field1, filed2, field3); I've had to do imports of a million or more records from CSV files, and PHP is a lot slower than MySQL at importing them :) -- Ray Hauge www.primateapplications.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It has been brought to my attention that with Perl and Ruby, you can use

Here is an example of how I would use such a feature.
I have a table of "customers".
I have a table customers "contact_locations".
This table has a reference ID back to the "customers" table.
Now, in my array of information that I build I have this.
$res = query('Select c_id, c_first_name, c_last_name FROM customers');
$customers = array();
while ( $row = fetch_assoc($res) ) {
$customers[$row]['contact_locations'] = array();
$SQL = "SELECT *
FROM contact_locations
WHERE c_id={$row['c_id']}";
$loc_res = query($SQL);
while ( $loc_row = fetch_assoc($loc_res) ) {
$customers[$row]['contact_locations'][] = $loc_row;
}
}
Now, contained within one array "$customers" I have all the information
that would be needed for displaying any type of information related to a
customer or a customers location.
By doing having this feature, I could build the ability to do xPath
searches within the base array. That would be nice.
Anyways, what do you all think? Worth it or not?
Jim Lucas
Maybe I don't get the new concept, but what would be wrong with:
// START CODE //
$cid = null;
$customers = array();
while ( $row = fetch_assoc($res) ) {
$cid = $row['cid'];
$customers[$cid] = $row;
$customers[$cid]['contact_locations'] = array();
$SQL = "SELECT *
FROM contact_locations
WHERE c_id={$cid}";
$loc_res = query($SQL);
while ( $loc_row = fetch_assoc($loc_res) ) {
$customers[$cid]['contact_locations'][] = $loc_row;
}
}
// END CODE //
Now you can easily reference all of your customers by ID and get any of
the data you want. I would actually just load the record I want from
the database and not chew up all that memory, but this is just an
example anyway.
I guess it could allow you to somewhat consolidate a two-dimensional
array down to a single dimension. In order to use the data, you'd have
to use array_keys() or something similar to use it though.
It's an interesting idea, but I don't know how practical it would be.

[PHP] Closures
I've been reading up on some of the parts of PHP that has been suggested could be improved so that I could be more well informed. One of the more "interesting" (for lack of a better word) suggestions is closures. I've used closures primarily in JavaScript, and they are handy in that context, but JavaScript handles events and other more dynamic situations like that. I can't really think of any good examples of why I'd want to use a closure instead of just calling functions or class methods in PHP. Variable functions and call_user_func*() have worked for any of the cases where I did need to be a bit more dynamic. I found a great summary of some discussion on the internals mailing list over here: http://devzone.zend.com/node/view/id/2013#Heading1 After reading that article through, I do like Wez's idea of how to create anonymous functions. The point about it causing confusion with people coming from other languages definitely applies though. This article also gives me a second idea for this post. How many people would want closures in PHP? In summary: Would you want closures in PHP, and why? -- Ray Hauge www.primateapplications.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'm not sure if this would solve your problem (my lack of java knowledge
is showing), but you can create objects either by creating a new
stdClass() object, or by using (object)NULL. Example:
test1 = 1;
$object->test2 = 2;
echo $object->test1 . "\n";
echo $object->test2;
?>
After trying to add a way to call a function from an object variable, I
have come to the conclusion that it's kinda ugly.
test = 2;
$obj->myTestFunc = "myTestFunc";
function myTestFunc () {
return "test";
}
echo call_user_func($obj->myTestFunc) . $obj->test;
?>
Does anyone have a link to some documentation about the stdClass? All I
could find was a bunch of bug reports and other stuff that wasn't what I
was looking for. I would have thought there'd be a page for it in the
manual, but I didn't find one there either.

The brackets are used to enforce that the entire contents between them
is a variable. It helps when you're using class members.
$example = "this is an {$example->text}";
It's also handy when you're putting variables in a heredoc.
I would suggest not using "{$_POST["param1"]}", like you said. It's
just going to make PHP figure out the string, then put the value in that
string. If you really wanted to make sure it's a string type then you
can do (string)$_POST['param1'].
The short answer is you can do it the way you're doing and everything
will work out just fine :)

You could use FPDF and FPDI to just load up the one page:

Just use importPage($thePageNumberYouWanted);

$pdf->AddPage();
$pdf->useTemplate($tpl, 0, 0);

$pdf->closeParsers();
header("Content-type: application/pdf");
header("Content-disposition: inline; filename=FileName.pdf");
header("Content-length: " . strlen($data));
echo $data;
I just realized that the version of FPDI I've been using is a little
old. There's a new update out, so some of the above code might change a
little.

just convert it to a timestamp with strtotime()
then you can manipulate it by adding/substracting

then convert back with strftime()

I believe you can also use strtoime()

$time = strtotime($inputTime);
$time = strtotime('-1 day', $time);
$outputTime = strftime('%Y-%m%d', $time);

Unfortunately it's not that simple. The equation sits in a DB and can be
anything - eg. ((([valuation]/[purchaseprice])/100)*100)/[numyears]
would be a typical field. [valuation], [purchaseprice] and [numyears]
gets replaced by relevant fields from user-entered data. But the system
is expandable which means I don't know what the equations, data or
fields are going to be beforehand.
I'm working on some kinda preg_replace function to sanitize the data at
the moment and then run an eval - arg I hate regexp! Ideally eval would
have some kind of sandboxing option, or you could limit the functions
available in an eval.

you might be able to leverage a call to expr on a bash sell. Just

[PHP] the class as a namespace
Is there a notion of the class as a namespace? My understanding is that the namespaces are intended to help organize the classes in large projects (and are not perfect). Is it considered good style to use a class simply to box related functions? For instance, a class called "files", contains functions I need for dealing with files - and the instantiated object is _simply_ used to access these functions - the instantiated object is not a file in itself. Thus what I do is not $INSTANTIATED_OBJECT->save(), but $INSTANTIATED_OBJECT->save($file) (though I could do the first if I first, say, do $INSTANTIATED_OBJECT->file = $file. Accessing the functions using the scope resolution operator (::) avoids the need to instantiate an object, but does not allow the use of $this, and $this can be quite practical in order to group common logic into shared methods within the class and thus make the other methods smaller in terms of code (of course, one could use file::save, file::delete instead of $this->save and $this->delete, but it makes renaming objects more difficult).

It's also a question if tasks really need to be reordered manually. If all tasks have a deadline, you might sort them by date. If some don't, you can provide them unsorted, until they get one. Sorting tasks by moving them up/down works when you have 25 tasks, but it does not work when you have 50, 100, 1 000 (if you are a team leader and have 5-7 people team) - in that case sort by date might be better.

Even if a software is not intended to be portable across operating systems, it is possible to use different file systems under the same operating system, and the rules might be different. Using file system level locks would require all possible file systems to be taken into account. And on top of that, the file systems are actively developed, so this is one more point to monitor, while maintaining the software. A less trouble free way is to create a file with the same name and extension ".locked" or similar, prior to read/write operations. Of course, this works only if the file is accessing only by one program, or if all programs accessing the file follow the same convention - but you should see that many file system level locks are advisory, as well.

[PHP] Enterprise
I just read an interesting article about enterprise software. One of the most common arguments against PHP tends to be "It's not enterprise ready." This article talks more about ruby, but it could be about any "non-enterprise" language as well. http://lists.canonical.org/pipermail/kragen-tol/2005-April/000772.html I recently got a new job at a hospital, and the "enterprise software" they have is no where near as high quality as it could/should be. This is my first job at a somewhat large organization (500+ employees) so I was kind of shocked at the state of their software.

I do not know your project, but to have many classes just to handle subscription, sounds a bit too much to me. Why don't you have a class called "subscription", which might even extend a class called "person" or "user" - the "subscription" class can have methods, for instance "subscribe" and "unsubscribe", and because "subscription" extends "person" or "user" - it already "knows" who is the "person"/"user". And then, for example, to subscribe a "person"/"user", you do - $subscription->subscribe($list_id); Other possible actions - $subscription->un_subscribe($list_id); $subscription->is_subscriber($list_id); $subscription->lists(); etc. This way class "subscription" "packs" the methods needed to handle subscription related activities, so in your own jargon, this "class" is a "package".

str_replace() also operates on arrays so there's no need for the loop:

My code was wrong in the first post, I just copied it straight from

if (get_magic_quotes_gpc()) {
stripslashes_array($_GET);
stripslashes_array($_POST);
stripslashes_array($_REQUEST);
stripslashes_array($_COOKIE);
}
set_magic_quotes_runtime(0);
set_magic_quotes_runtime() has no effect on magic_quotes_gpc.
function stripslashes_array(&$arr) {
foreach (array_keys($arr) as $k) {
$arr[$k] = stripslashes($arr[$k]);
}
}
This function breaks arrays, ignores keys, and takes into account none
of PHP's inconsistencies with magic_quotes_gpc.
As I said before, if you need to do it at runtime, use the PHP_Compat code.
Here's the two relevant files, if you can't use the PEAR installer:
http://cvs.php.net/viewvc.cgi/pear/PHP_Compat/Compat/Environment/_magic_quotes_inputs.php?revision=1.3&view=markup
http://cvs.php.net/viewvc.cgi/pear/PHP_Compat/Compat/Environment/magic_quotes_gpc_off.php?revision=1.7&view=markup
I tried searching for setini, but came up with nothing, except this:
setIni('magic_quotes_gpc', 'Off', $inifile); // didn't work: unknown
function
ini_set() is probably what you're thinking of, but magic_quotes_gpc is
applied before your script is executed so it will have no effect.
That's why the only option at runtime is to reverse it.

Don't forget making it secure. Here is one of my questions people can use if they like. Feel free to re-word it.

After the time limit for a session has been reached, then the garbage collection will usually clean it up. The only way to not break a session is to never clean up the session files, or set the timeout to a day or so. I wouldn't suggest sending the PHPSESSID via a form. That leads to people being able to hijack sessions ; After this number of seconds, stored data will be seen as 'garbage' and ; cleaned up by the garbage collection process. session.gc_maxlifetime = 1440 HTH -- Ray Hauge Programmer/Systems Administrator American Student Loan Services www.americanstudentloan.com 1.800.575.1099 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You could create a script that basically just does apc_clear_cache() et all.
and call it from lynx, curl, wget, etc. and throw that into a cron job. That
would technically get you to call the script from the cli, but it should
clear the webserver cache.

I use Slackware linux, and XMLRPC is not compiled in by default with my distro, so I'm compiling PHP myself. It's always been a simple enough task.

Now I get this error message: undefined reference to `libiconv' when compiling PHP. I did some searching, and the only thing I've found in reference to this error was a bug in version 4.3.10. Has anyone run into this issue, or have some suggestions?

I'd take a look at shell_exec. There'sa comment about capturing stderr. I'm
not sure if shell_exec captures stderr, but it should at least point you in
the right direction. Just do a search for stderr and you should find some
good info.

Best example I found was:
$shell_return = shell_exec($shell_command." 2>&1");
that should redirect stderr to stdout and thus you'd get both.

LDAP can authenticate with Active Directory just fine:
http://www.google.com/search?hl=en&q=php+exchange+ldap+authentication&btnG=Google+Search
or
http://www.google.com/search?hl=en&lr=&q=php+active+directory+ldap+authentication&btnG=Search
The question is how secure is it. You can set up LDAP to use SSL, so that
would make it more secure. Kerberos is more secure than LDAP, and you
_could_ set it up so that the browser forwards the ticket on to mod_kerb for
authentication, thus not needing a sign-on other than to the domain. From my
experiences that isn't exactly easy to set up though.

Re: [PHP] Emphasizing first letter of string?

Hi,
It is getting late, and I do not think I am thinking clearly...
What would be the best way to wrap tag around the first
letter of a string?
I know it has to be a combination of str_replace() and substr(), but
due to my level of sleepiness I am having a lot of trouble working
this one out...
Basically, if a config variable == true I want my script to loop
through an array of strings and emphasize the first letter of each
string.
Make sense? Sorry, I am pretty sleepy... Hmmm, I am betting I will
discover the answer as soon as I send this email. :D
Anyway, any help would be great!
Cheers,
Micky

Re: [PHP] Overriding core functions
You can't just define a new function with the same name. The only way I
know to literally redefine the function is using the runkit extension -
http://pecl.php.net/package/runkit
That allows you to rename functions as well as moving them, so you could
rename it to something like old_mysql_query() then define your own
mysql_query().

work OK.
The snag I see coming at you like a tonne of bricks is 'how do you
call the original function once you have overridden it.'. This like
like calling SUPER. in Java.

Yes, that could solve it. However, my question was if I can override the
core functions :) Similar that I can do Parent::myFunction() in a
subclass,
I want to do that, but with core functions :)

Hi,
I want to add some functionality when calling the mysql_query():
function my_query($Query) {
//do stuff before
mysql_query($Query);
//do things after
}
// or something like:
class PeteDB {
var $conn;
function PeteDB($db, $usr, $pwd, $etc) {
$this->conn = mysql_connect($db, $usr, $pwd, $etc);
if (!is_resource($this->conn)) die('db is useless'); //
trigger_error()
}
function query($qry/*, $args*/) {
// do stuff
$r = mysql_query($qry, $this->conn);
// do more stuff
return $r;
}
}
/*
tada!
hint: always use some kind of wrapper for things like db related
functions
(because it allows for stuff like this and, for instance, makes it alot
easier to
switch dbs - because you only have to change code in one place, not
counting
any db-specific
sql floating around your app)
*/
This would just be for one project where I want to record all
Queries and
the result of them, creating an own logging function.
I did a lot of Google, but no article that I found that take care of
this
subject.

Brad Bonkoski wrote: Some already good workarounds given for this question... BUT. Is it even possible to override a core function? Like I wrote a function called 'exit' and I got a parser error, which leads me to believe it is not even possible to override the core functions. Is this true of ALL PHP functions? -B 'exit' is a language construct like 'echo', so I don't think you'd be able to redefine that even with runkit.
