Richard Heyes has this quick new post offering the download of his own, self-created PCRE "cheat sheet".

Inspired by the great stuff at AddedBytes.com, here's a dedicated PCRE cheat sheet. The PHP cheat sheet at AddedBytes is fine enough, but PCRE goes way beyond what is there. Hence, this. Enjoy.

It's a handy, one-page document that lists the PHP preg_* functions, sample character classes, meta characters, pettern modifiers, quantifiers, point-based assertions and some subpattern modifiers thrown in as well.
