PhpStorm代码完成不显示核心类/扩展 [英] PhpStorm code completion doesn't show core classes/extensions

问题描述

我在使用PHPStorm时遇到了麻烦。我刚开始新项目创建了几个我自己的类，其中一个我创建了PDO对象。

I'm having trouble with PHPStorm. I just started new project created a couple of my own classes, in one of them I created PDO object.

$this->cnn = new PDO("sqlite:db/base.db");

现在，当我想通过crtl + whitespace看看这个对象有什么样的方法时，我得不到建议。然后我试着看看我可以使用的课程列表。

Now when I want to see what kind of methods this object has via crtl + whitespace, I get no suggestions. Then I tried to see the list of classes available to me with.

$newClass = new

当我按下ctrl +空格时，它只显示我创建的类。

And when I pressed ctrl + whitespace it only showed me the classes I created.

所以问题是，我需要做什么，让PhpStorm看到所有可用的类（不仅仅是我创建的类）。

So the question is, what do i need to do, to make PhpStorm see all the classes that are available (not just the ones i created).

PS当我按住Ctrl +单击PDO（带下划线）时，它表示该类未定义

P.S. when i ctrl + click on PDO (which is underlined) it says that class is undefined

P.P.S。在项目设置中我选择了php 5.4语言和选择的解释器（php 5.4.7，使用xampp）

P.P.S. in project settings i have selected php 5.4 language language and selected interpreter (php 5.4.7, using xampp)

推荐答案

我是解决了这个问题。文件>无效缓存就行了！

I've solved the issue. File > Invalidate Caches did the trick!
