`Note: is_object(null) returns false
This should actually be part of the input/output specification at the top of this page.

`Unserializes data as returned by the standard PHP serialize() function. If the unserialized object is not an array, it will be converted to one, particularily useful if it returns a __PHP_Incomplete_Class.
obj=unserialize(obj = unserialize(obj=unserialize(data); if(is_array($obj)) return $obj; $arr = array(); foreach($obj as k=>k=>k=>v) { arr[arr[arr[k] = $v; } unset($arr['__PHP_Incomplete_Class_Name']); return $arr; } ?>`
