Description:
------------
When testing arrays for a key's existance with isset() or empty(), a float key is treated as zero in PHP v5. This behavior differs from PHP v4.3.6.

Reproduce code:
---------------
$MyArray[0] = 'zero';
$key = (float) 5;
$isset = isset($MyArray[$key]);
var_dump($isset);

Expected result:
----------------
bool(false)

Actual result:
--------------
bool(true)
