in thread Reg expression to replace URLs with Anchor tags in Tweets

Actually preg_replace in PHP uses Perl regex.
No, it doesn't. It really doesn't. It might use "PCRE", which despite the name, is not Perl, nor even very Perl Compatible.

This is why you're getting pushback. You are operating from a false claim.
