严格的标准:API_RATING::multiDelete(） 的声明应与 API::multiDelete($ids

我最近将我的一个站点移动到运行最新版本PHP的新专用服务器上。 在站点的基于php的知识库部分中，我收到以下错误：

严格的标准：API_RATING：：multiDelete(( 的声明应该与/home/givebrad/public_html/kb/lib/api/class.rating.php 中的 API：：multiDelete($ids = 0( 兼容，第 156 行

第 156 行是文件底部的最后一个结束 }。 以下是班级评分的代码.php。 谁能帮我弄清楚如何解决这个问题？
