representing the dependence of classes

Hello!

Does PhpStorm a tool to search for classes?
Does PhpStorm a tool that shows the dependencies of classes?

I have a class. In this class, other classes are used.
For example:

myClass {

public function foo () {
.....
$ subClassA = new Front_Model_SubclassA ();
$ subClassB = new Front_model_SubclassB ();
...

}

public function bar () {
...
$ myTest tools_test :: = getTest ();
...

}

}

I would appreciate any information.

Yours sincerely, Stephan
