along with eregi(), but it can (should) be easily adapted to a syntax compatible with preg_match().

I'm wondering two things: 1. Is there a performance difference between ereg() and eregi()? I'm thinking it might be better to change [a-z] to [\w].

Would probably be better to use \w, but best overall to just use preg_match(). The preg_* functions are faster than the ereg* functions...

I remember a large discussion about this a while back. Archives may be useful.

I couldn't find anything, but I was pretty sure it had been discussed before as well. Happen to know the subject of the thread?

I looked through 40 pages of archives and couldn't find it either. :) It had to deal with validating an entire name and capitalizing it with the whole McNab vs MacNab vs O'Reilly vs Marco de Blabla or whatever. If I find it, I'll forward it your way. -- ---John Holmes... Amazon Wishlist: www.amazon.com/o/registry/3BEXC84AB3A5E/ php|architect: The Magazine for PHP Professionals – www.phparch.com
