The PHP Cheat Sheet
Programmers often complain about PHP's inconsistant naming conventions. And sometimes there is simply too much to remember (eg date formatting, regular expression syntax). Fortunately David Child took the time to create a PHP "cheat sheet" for us to refer to. The PHP Cheat Sheet is designed to be printed on an A4 sheet of paper and live by a developers desk. If you use PHP it is worth a look.
