php项目的索引页面不显示任何内容

Question

我从 sourceforge.net 下载了一个名为 Employee Scheduler 的 php 项目。问题是，index.php 应该是主页，但是当我通过 localhost 访问它时没有显示任何内容。我计算机中的其他 php 项目在我访问它们时正在运行，但这个员工调度程序除外。我很确定我也在访问正确的文件夹，在

中访问它

localhost/scheduler/index.php

甚至在同一目录中创建一个测试 php 文件并访问它。测试 php 文件有效，并且 index.php 仍然没有显示任何内容。这可能是什么问题？

我在我的 Windows 7 计算机上使用 WAMP。

编辑：

我在 php 文件的第一行包含了error_reporting(E_ALL);，但它仍然没有输出任何内容。什么给了？

我会把 index.php 的内容贴在这里：

Answer 1

尝试在error_reporting(E_ALL)之后添加以下行；

ini_set("display_errors", 1);
