PHP array: count or sizeof?

To find the number of elements in a PHP `$array`, which is [faster/better/stronger][1]? `count($array)` or `sizeof($array)` ? Edit ---- Thanks to Andy Lester, I have refined my question to mean from a multilingual perspective. The manual commenters say > "[sizeof] does not mean the same in > many other languages based on C" Is this true? [1]: http://en.wikipedia.org/wiki/Harder,_Better,_Faster,_Stronger
