[SOLVED] Request : Help on preg_match_all()

[sameer1122]

I have a string - http://www.youtube.com/watch?v=xxxxxxxxxxx

 

Can somebody help me with the code to retrive xxxxxxxxxxx from the string

 

I tried

 

$pattern = '/youtube\]http://(?:www\.)?youtube.com/watch\?v=([0-9A-Za-z-_]{11})[^[]*\[/youtube\]/s';

preg_match_all($pattern,$text,$matches);

 

But it doesnt work and gives the error - preg_match_all() [function.preg-match-all]: Unknown modifier '/'

 

Thanking you
