Description:
------------
cannot deserialize an serialized output...

the serialized object is an array of query_result objects which contain an "result" element which is an array of simple objects.

Reproduce code:
---------------
<?

class query_result   {
	
	public $affected_rows = 0; 
	public $num_rows = 0; 
	public $insert_id = 0;

	public $result = array(); //pdo result
	public $pointer = 0;
}

$dump = unserialize(file_get_contents("dump.txt"));

if($dump == NULL) {
    echo "error";   
}
else if(is_array($dump)) {
    echo "not error";
}
else {
    echo "huh? {$dump}";
}

?>

Expected result:
----------------
not error

Actual result:
--------------
error
