Re: [PHP] Regex in PHP

Hi,

> and the case insensitive versions are a hair faster still ;)

Are they? I always thought that case-sensitive functions were faster 
because they have to test fewer comparisons. Eg To test if i == I in a 
case-insensitive fashion requires two comparisons (i == I and i == i) 
whereas a case-sensitive comparison requires only one (i == i).

Cheers.
