PHP 对象转数组 Object转array

//调用这个函数，将其幻化为数组，然后取出对应值
    public static function object_array($array)
    {
        if(is_object($array))
        {
            $array = (array)$array;
        }
        if(is_array($array))
        {
            foreach($array as $key=>$value)
            {
                $array[$key] = self::object_array($value);
            }
        }
        return $array;
    }
