If you want to check if an array has zero length, you should just use "!", as I did in that commit, so that a typo in the variable name will still give you the appropriate warning. Or if you want to make it explicit that you are checking array length, you can use !count($array). empty() should only be used when you are sure you want to ignore warnings. -- Tim Starling
