【问题描述】：
我想在 localhost 上运行一个 PHP 网站。我设置了服务器并导入了数据库，但出现以下错误...我从客户端 c_panel 公共 HTML 文件夹下载了网站并导出了数据库。我必须在前端进行更改并且我不知道 PHP（我是一名 Node.js 开发人员，所以如果你可以参考它来帮助我。）。我只想在本地启动网站，这样我就可以做前端的更改。我的 app/Models.php 中出现以下错误

【问题讨论】：
-
检查
Response类中的redirect method是静态方法还是非静态方法？如果缺少静态关键字，请在方法名称前添加static。 -
<?php namespace SB; class Response { public static function back(){ echo '<script>window.history.back();</script>'; } public static function go($a = -1){ echo '<script>var x = history.length; if(x>3){window.history.go('.$a.');} else{window.location.href="'.URL.'"}</script>'; } public static function json($req = []){ header('Content-type:Application/json'); echo json_encode($req); } function redirect($endpoint){ @header('Location:'.URL.$endpoint); } }这是响应类
