Yes, the actual regex matching code is quite faster. The code that does replacement though was mostly taken from ereg_replace(), with some modifications for the PCRE stuff. I don't know right now how it can be optimized more.

I think the main reason why Perl is so much faster than ASP & PHP in that benchmark is because regular expressions are part of the language syntax. 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. Andi --- Andi Gutmans <andi@zend.com> http://www.zend.com/
