Listen to all errors, big and small

Always set your PHP error level to the most verbose level, E_ALL. All too often people don't realise that PHP is outputting various complaints about variables not being set, etc, which you can just do away with entirely by cleaning up your code. While you are editing your php.ini file, it would also help to disable all the extensions you don't use - they are just chewing up memory otherwise.
