Regexp Kung-fu

There are two answers guaranteed to show up on nearly every PHP question on Stack Overflow - use the mysqli/PDO extension instead of the deprecated mysql one (to avoid SQL injection), and that you can't parse HTML with regular expressions.

With that in mind, my favorite two answers:

How PDO is still vulnerable to SQL injection attacks by Anthony Ferrara
Parsing HTML with regular expressions by Tom Christiansen

The silver searcher

The silver searcher is basically ack, rewritten in C to be crazy fast. If you're regularly using grep to search a codebase, this is probably a much better idea.

kellan points out this interesting old TPJ article on problems with localization and gettext. the solution isn't really any good, but the problem is real
