PhpStorm-索引文件不存在错误
[英]PhpStorm - Index file doesn't exist error
问题描述
I am trying to familiarize myself with PHP and PhpStorm. 
我正在尝试使自己熟悉PHP和PhpStorm。 When I try to run any PHP file it gives me following error: 当我尝试运行任何PHP文件时，出现以下错误：
404 Not Found: Index file doesn't exist.
And when I try to execute my PHP code via small HTML code then it doesn't stop at breakpoint. 当我尝试通过小的HTML代码执行我的PHP代码时，它不会在断点处停止。
Is there a config which I am missing? 有没有我所缺少的配置？

Recently i faced the similar problem. 最近，我遇到了类似的问题。 In fact phpstorm is able to open files by two ways: 实际上，phpstorm可以通过两种方式打开文件：
- First create/open project and then open files within the project (this is the prefered way) 首先创建/打开项目，然后在项目中打开文件（这是首选方式）
- Opening external files 打开外部文件
To open an external file do one of the following:
Choose File |
So if you open your files using the first way (through project) you shouldn't face the "404 Not Found: Index file doesn't exist." 因此，如果您通过第一种方式（通过项目）打开文件，则不会遇到“找不到404：索引文件不存在”的问题。 problem. 问题。
But when i use the second one (Opening external files) i see the same problem. 但是当我使用第二个（打开外部文件）时，我看到了同样的问题。
