AFAIK, ereg* is slower than preg*, that may be where you got this from,
but the PCRE library is lightning fast.
I'd recommend Mastering Regular Expressions by Jeffrey Friedl (O'Reilly) -
it gets a bit mind-numbing in places (talking about the mechanics of how
different regex engines work) but it's a great reference and is quite
readable (given the subject matter).
Cheers,
Andy
