One thing I keep forgetting is that PHP has a built-in function for removing duplicate items from an array; I usually find myself about halfway through writing such a function when the lightbulb goes off.
$original = array ('pie', 'cake', 'cookies', 'cake'); $clean = array_unique($original);
The $clean array above would contain one less reference to cake than the $original array.
