Re: [PHP] is_prefix() - checking wheather $A is prefix for $B
You should benchmark and tell us - anyway, just looking at the code, I'd
say 'is_prefix2()' is faster since there's 1 function call instead of 2

An alternative approach is the AJAX [1] one: you set up a JavaScript 'setInterval' and call an "AJAX" function that makes a query to the PHP script that updates the session (with the current timestamp, user_id, whatever...) Ok, I don't know if this makes much sense, but you end up with a script that gets executed (without user interaction) every 'n' microseconds, so your session data is always up to date (at maximum, with a delay of 'n' * 2 microseconds). The bad side of this is that you have a script that gets executed quite often for every user visiting your pages: but, if you keep it minimal (a couple of queries) the overhead isn't that much and you get a *near-to-real* number of open sessions. I hope I made some sense: in any case feel free to ask, I just developed something like this for a web site I'm working on (but we're still in alpha), so if you want to see it in action, lemme know.

Actually this doesn't seem right, the join should be:
$values = join("', '", $array); # notice the ' inside the "
In addiction, I would (SQL)escape the values joined: supposing you are
using MySQL, I'd do:
$values = join("', '", array_map('mysql_real_escape_string', $array));

I don't know if it may help you, but why don't you set a constant in a
config file included by all your scripts to the CRLF value you want (if
you want it dependant on the OS you can use http://php.net/php_uname)
and then you append this constant to all your strings?
Example:
- config.inc.php:
define('CRLF', ( strtoupper(substr(PHP_OS, 0, 3)) === 'WIN' ? "\r\n" :
"\n" ) );
- other_script.php
require_once 'config.inc.php';
$string = 'Hi! My name is Pippo!' . CRLF;
Or something like this... ;-)

When I need to use dates in PHP *and* MySQL I usually use the UNIX timestamp (seconds since the epoch, that is, the PHP http://php.net/time output). This way I can (quite) easily calculate date differences etc. (usually all the calculations are done in PHP, also when building SQL queries). As I said, just my 0.02 euros...

(Kinda like GMail and stuff like that?) You can create a DIV in your page that contains the *output* (maybe an image with the width set to the percentage of mails sent): the content of this DIV is updated by another script (the one that sends the email) that gets called (via JavaScript) at specific intervals with a specific query (in your case, the messages to send). This way your main page never gets reloaded and you see a nice progress bar in your DIV. I know it sounds a bit difficult, but it's a cool "technology" and after the initial difficulties it can be really useful. As a start, have a read here: http://en.wikipedia.org/wiki/AJAX HTH, cheers!

Re: [PHP] Multiple permisions, different sessions.
Hi Pablo it really depends on what you want to do. I mean, if you want a hierarchy of users (like: guest, normal, administrator, root) or you wnat to limit certain users to an "area" of your site and certain others to another area (no hierarchy here, just "fences"). Anyway, in both cases I suggest you to check at the beginning of every script of the users is allowed on that page. What differs is *how* you decide if the user is allowed on the page: - for a hierarchy-based system, you could assing a number to every users (guest: 100; normal: 1000; administrator: 1; root: 10) and compare this number with the "access number" of your page (saying for example that your "orders.php" can only be accessed by users >= 1, so only administrators and root) - for "fences", what I would suggest is to create groups, assing users to these groups (based on what they can see) and then check at the top of your PHP page if the current user belongs to an allowed group. Obviously I made it quite simple here and there could be other "twists" to this thing (we are talking about a read-only system, but you could specify also "edit" permissions, kinda like the ones you have on files on Linux): anyway, I hope it helped a bit.

Re: [PHP] File Copy
Chris Dowell wrote: Aidal Could you post the relevant parts of your code so we have a little context to work in? You say you're copying a file from one location to another on the same server. If this is the case you are very unlikely to be in need of the ftp family of functions, which are only valid for use over an established ftp connection. You can indeed establish an FTP connection to your local server - provided it has an FTP server running. The files are actually copied by Apache (or whatever Web server he's using), so this is why the server becomes the owner. I suspect that the file is indeed now owned by the webserver has it changed from aidal:somegroup to nobody:nogroup or something like that? I guess this is the problem Aidal is experiencing. In order to maintain file ownserships, what he can do (since he doesn't have PHP 5) is "copy" the file with 'ftp_fput()' [http://php.libero.it/manual/en/function.ftp-fput.php]. That is, he opens the files he wants to copy and PUTs it via this function. Since he is logged in - using 'ftp_connect()' and 'ftp_login()' - the files will be owned by the user he used to login.

Hi NG.
I'm experiencing some problems when trying to copy a file from one location

example:
dir1/subdir1/some_image_name.jpg --> dir2/subdir2/some_new_image_name.jpg
When I do this the file permissions changes and I'm no longer the owner of
the file. I tried to use chmod('the_new_file', 0777); but it doesn't work,
because chmod() wont let me change the permissions since I'm not the owner
of this new file.
The owner should now be the user the Web server is running as.
To change file ownerships you need to use the PHP FTP functions.

This is what you are asking PHP to do.

Re: [PHP] Add to regex help
Uhm, I guess you are looking for links (following a 'href') in your HTML page, so why
don't you just do something like:
preg_match_all('/href=[\"\']?([^\"\'>\s]*)[\"\']?/i', $url, $matches)
(note the '\s' added inside the bracket that should match the link, as you could have:
- that is, a link "terminated" by a white space)

Re: [PHP] how to create multiple selects within php
You can do something like this:

and then in your PHP:
Anyway, you can catch this only *after* the form is submitted: in case you want to block
the user from submitting the form if the 'foo' select is empty you need to use some
javascript:
<br>
function check_form(form) {<br>
if (form.foo.value == '') {<br>
alert("C'mon!!!");<br>
return false;<br>
}<br>

if someone can point me to an actual working example of php code that

Re: [PHP] Split haystack at nth occurrence of needle?
Hi
if you want the *rest of the string from the nth *, I think
'preg_match_all' with PREG_OFFSET_CAPTURE can help you (see
http://www.php.net/manual/en/function.preg-match-all.php)
You could do something like:
$string = "onetwothreefourfive";
$count = preg_match_all('/([^<]+)/', $string, $out,
PREG_OFFSET_CAPTURE);
and you will have an array of 2 arrays, where the first one contains the
full pattern matches and the second one contains arrays for each string
matched *and the starting offset* of that string.
Therefore, to know where the 2nd ends (so we would get 'three') all you
have to do is:
$out[1][1][1] => 14
