Re: [PHP] Unexplained Issue Using Regex
Haven't tested your code but from a rapid look it would work.
The issue here is that I don't understand why my expression doesn't catches
the full match and emits the first character?

Re: [PHP] Unexplained Issue Using Regex
I'm not looking for other ideas, the main thing here is that I have about
30-100 regex's in the database and the script fetches them and applies them
to the string. I can't build again the engine and I'm not going to do that.
I'm trying to solve my problem ;) If you have any ideas regarding my issue
and not going in another way this would be very appreciated.

Nitsan,
I think it's because you're referencing the capture group with index
instead of index 2. Also, I don't understand why you have the pipe
(|) character in your regex string... is that part of your engine?
This code:
$orig = 'http://www.zshare.net/video/541070871c7a8d9c';
$matches = array();
preg_match('#http://(www\.)zshare\.net/video/([^/]+)#', $orig, $matches);
echo $matches[2];
Grabs the correct match:

The regex pattern works with the pipe char, but it is unnecessary and
may lead to some strange behavior.
Hope this helps,

Re: [PHP] Unexplained Issue Using Regex
Thank you Todd, I also want to capture when I don't have the www in the
beginning of the URL.
For instance, try to execute your code with
$orig =
'http://zshare.net/video/541070871c7a8d9chttp://www.zshare.net/video/541070871c7a8d9c
';
That's why I used (www\.|), but I'm not a regex expert and I'm sure there a
way better solutions to this problem.

http://www.regular-expressions.info is your best friend. Spend an
afternoon playing around on it... that's really the only advantage I
have over someone who hasn't.
Anyway, you can make that entire group optional with the ? character like so:
#http://(www\.)?zshare\.net/video/([^/]+)#
And if you don't want it to be captured, making the URL suffix index 1
instead of index 2, do this:
#http://(?:www\.)?zshare\.net/video/([^/]+)#
Any group that begins with ?: will not be captured in a match index. To recap:
$pattern = '#http://(?:www\.)?zshare\.net/video/([^/]+)#';
$orig = 'http://zshare.net/video/541070871c7a8d9c';
$matches = array();
preg_match($pattern, $orig, $matches);
echo $matches[1] . \n;
$orig = 'http://www.zshare.net/video/541070871c7a8d9c';
preg_match($pattern, $orig, $matches);
echo $matches[1] . \n;
Produces this output:
541070871c7a8d9c

Re: [PHP] Unexplained Issue Using Regex
Got it, thank you Todd.
I usually tend to use string based functions instead of regex, but sometimes
regex is a better option.
