is there something wrong with regex?

Bro, I can't use regex, if you want, I can code it my way. Will use String Tokenizer.

fixed it guys sorry for the trouble

[sloddl]

change this:

preg_match_all('#<youtube>(.*?)</youtube>#i', $content, $link_matches);

to this:

preg_match_all('#<youtube>(.*?)<\/youtube>#i', $content, $link_matches);

if it still won't work... then post the error which you get.

Raj solved it. Apparently he was stuck in a loop. Happens to all of us.
Best of luck with your project mate.
