How to open recently closed file in PhpStorm?

In addition to Umur's answer, PhpStorm has the convenient Ctrl-E shortcut for Recent Files which is already bound by default. It's not restricted to closed files, though, but it's still very convenient to move around between opened or recently closed files.

There is such a command exists already but it does not have a shortcut. I always assign Ctrl+Shift+T for it too.

Press Ctrl+Alt+S to go to settings and search for reopen clo...and assign a new shortcut to the command under Keymapsection.

Additionally this may come in handy too.

To open a recently opened file, choose View | Recent Files on the main menu or press Ctrl+E. Then select the desired file from the Recent Files pop-up window, that opens.
