Thus the regex's are compiled at compile time. In PHP, although there is a regex cache for PCRE regex's there is more of an overhead as they aren't embedded as part of the language. Right, and that's the reason Perl can do a couple more tricks with regex's. Man, Perl internals scare me. I had to wade through pp_hot.c to figure out some regex stuff and I swear I'd never seen such convoluted programming before.

I looked at the Perl sources a few years ago before Zeev and I started writing the PHP 3 engine. After a few minutes I erased the sources because they were so bloody cryptic. Andi --- Andi Gutmans <andi@zend.com> http://www.zend.com/
