Php 服务器错误500；我的代码或服务器错误？

php html mysql

Php 服务器错误500；我的代码或服务器错误？,php,html,mysql,Php,Html,Mysql,你好，我正在做一个基本的预算系统。在过去的一周里，我一直在将文件从本地主机移动到Web服务器，并且遇到了服务器错误。通常，我可以通过稍微更改代码（声明字符集或去掉php的某些部分）来解决这些问题，但是现在我有一个页面不工作，另一个页面工作，它们有几乎相同的php，唯一的区别是变量。以下是我对不起作用的代码： <?php header('charset=utf-8'); session_start(); include_once 'checkLogin.php'; include_once

你好，我正在做一个基本的预算系统。在过去的一周里，我一直在将文件从本地主机移动到Web服务器，并且遇到了服务器错误。通常，我可以通过稍微更改代码（声明字符集或去掉php的某些部分）来解决这些问题，但是现在我有一个页面不工作，另一个页面工作，它们有几乎相同的php，唯一的区别是变量。以下是我对不起作用的代码：

$mid = $_GET['mortgageId'];//to use to get other stuff

ini\u集（'display\u errors'，1）error\u reporting（）。在开发和测试代码时一定要这样做首先检查文件权限，Web服务器应该对脚本具有读取权限这只是一条开发人员控制台消息。请检查您的日志。
