php 将解json的stdClass转为数组形式

function std_class_object_to_array($stdclassobject)
{
    $_array = is_object($stdclassobject) ? get_object_vars($stdclassobject) : $stdclassobject;
    foreach ($_array as $key => $value) {
        $value = (is_array($value) || is_object($value)) ? std_class_object_to_array($value) : $value;
        $array[$key] = $value;
    }
    return $array;
}
