Regular expressions

Last week I ordered The Definitive Guide to Apache mod_rewrite by Rich Bowen on Amazon UK.

It arrived today, and I’m nearly one third through it already.¬† It’s a really well written, easy to read book about that mysterious “Swiss Army Knife” or URL manipulation.

For those who don’t know, mod_rewrite is what makes WordPress web addresses (URLs) so friendly.

So this evening I’m playing with a cool application called The Regex Coach, which allows you to play with regular expressions (often shortened to ‘regex’) and see how they react to some example text that you give it.
