preg_match fails on vb page
 

I calling a regex as part of some custom code. The expression fails when called on a vb page, and works just fine on a pure php page (with the same input string).

I am guessing there is something in the vb environment that affects how regex are called. Any idea what that might be?

Thanks for your help

Hmm...is your php page running on the same web server as vbulletin? Can you post the code segment and the string?

Never mind, my fault all along.
I was dealing with HTML encoded strings on the vb side, and pure ascii on the test side.

I did find, however, that VB is disabling the regex mem/runtime limit in \includes\init.php. Be careful, if you run expensive regular expressions.
