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](http://stackoverflow.com/questions/134099/are-pdo-prepared-statements-sufficient-to-prevent-sql-injection/12202218#12202218) by Anthony Ferrara

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.

the cpan testers matrix is a really good tool (especially for a cpan tool) - an at-a-glance report of how well your various modules are testing (and motivating me to fix the failing ones)

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

aside from the final calculation being highly dubious, the perl module dependancy viewer is pretty neat
