Is there a way for PhpStorm to show documentation for user defined methods that have been included using e.g. include_once()?
So far I've only been able to successfully present documentation lookup when the method's phpDoc is residing in the same file, which is very limiting when trying to understand what a method does, especially when it has been included from another file.
What seems to be working ok, which is as I expect, is that I can invoke code completion by typing a part of the same method's name, then hitting Command+Space and get a suggestion of the method I want, along with a very short hand documentation description of its arguments.
I've been banging my head at this problem for half an hour now and would like to know if there is any way at all that accomplishes what I want to do, which is to display documentation for methods that are globally available.
