In PhpStorm, Can I see php file tree ?

Hello!

Example, in index.php content: require_once ('./file1.php').
Then file1.php content: require_once ('./file2.php').

In PhpStorm, Can I see php file tree ? (php file hierarchy only)

Tell me please about it.

Other words, not a simple hierarchy of directories and files, but namely php file hierarchy only.


Thank you.
