Question

我在phpstorm 8.0.3上设置了yii2项目。我的命名空间结构如下：

backend\
  controllers
  models
  ...
frontend\
  controllers
  models
  ..
common\
  controllers
  models

我在项目中使用了composer，并在vendor文件夹中安装了各种依赖项。

每当我尝试使用不在同一基本命名空间（frontend，backend或common）中的类时，我会得到一个未定义的类错误。奇怪的是，类的名称空间是自动完成的：

另一个奇怪的是，如果打开定义了类的文件，某些类的未定义类错误就会消失。

Answer 1

看起来PHPStorm缓存有点被破坏了。我最后通过转到File - ＆gt;来使缓存失效。 Invalidate Caches/Restart。这删除了我的历史，但修复了未定义的类问题。

Answer 2

您必须在use部分中声明nedded类或命名空间。例如，如果您需要使用BaseController命名空间中的custom\controllers：

<?php
namespace frontend\components;

// Add this line
use common\controllers\BaseController;

class Controller extends BaseController {
}

我不得不重置我的 PHPstorm 来解决“找不到类”的问题。

请小心，它可以让一切正常，但它还可以让您备份当前的设置。在那之后，一切都被硬重置，现在又可以正常工作了。

我认为你在使用composer autoload时遇到了一些问题。试试：

composer update

Answer 5

这是由于我的PHP语言设置而发生的。我是通过删除我的一个类中的名称空间发现的。错误更改为“标量类型仅在PHP 7中可用”。

转到SELECT DISTINCT code from TempTableExcelFile WHERE code in (SELECT Code from tblpeople)。将File -> Settings -> Language & Frameworks -> PHP更改为语言版本7或更高版本。

编辑：之后，PHP language level间歇性地以Insert -> Getters and Setters而不是mixed的形式生成函数和注释。我不知道为什么会这样，但是我手动重新创建了所有字段，从而解决了该问题。

如果类在不同的命名空间中，则为未定义的类
