严格标准：API_RATING::multiDelete() 的声明应该与 API::multiDelete($ids = 0) 兼容

Question

我最近将我的一个站点移到了运行最新版本 PHP 的新专用服务器上。在我网站的基于 php 的知识库部分中，我收到以下错误：

严格标准：API_RATING::multiDelete() 的声明应与第 156 行 /home/givebrad/public_html/kb/lib/api/class.rating.php 中的 API::multiDelete($ids = 0) 兼容

第 156 行是文件底部的最后一个结束 }。下面是 class-rating.php 的代码。谁能帮我弄清楚如何解决这个问题？

<?php
require_once(dirname(__FILE__).DIRECTORY_SEPARATOR.'class.api.php');

            $questionObj->negvotes--;

这个功能：

function multiDelete($ids) {

应该和它的父函数相同，在API类中找出相同的函数，参数的数量、默认值和类型应该相同；
