How are you grabbing all the data from the page?

It's going to use a bit of memory to search an entire page with a
regular expression. It's probably going to be slow(er) no matter how you
slice it.

I would use the PCRE functions; preg_match_all() probably..

Look over these:

I think you'll want to use m (and g is default, as the comment says).

Something like this may work:


/* untested */

while(list(,$match) = each($matches[0])) 
   print "$match\n";
