PhpStorm 代码完成不显示核心类/扩展

我在使用 PHPStorm 时遇到了问题.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 + 空格查看此对象具有哪些类型的方法时，我没有得到任何建议.然后我尝试查看可供我使用的课程列表.

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，我需要做什么才能让 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).

附:当我 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

附言在项目设置中，我选择了 php 5.4 语言并选择了解释器(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)
