I need to use the regex pattern located here:
http://regexlib.com/REDetails.aspx?regexp_id=1374

I implemented it already, but I get an error message :

Warning: preg_match() [function.preg-match]: Unknown modifier '/' in ....


Here is the code I need to use:

$link = email address or url

if (!preg_match('/(([\w]+:)?//)?(([\d\w]|%[a-fA-f\d]{2,2})+(:([\d\w]|%[a-fA-f\d]{2,2})+)?@)?([\d\w][-\d\w]{0,253}[\d\w]\.)+[\w]{2,4}(:[\d]+)?(/([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)*(\?(&?([-+_~.\d\w]|%[a-fA-f\d]{2,2})=?)*)?(#([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)?/', $link))
            {
                  echo $link;
                  //header("Location: http://www.domain.com/");
                  exit;
            }
