Seriously, this hasn't improved at all since I first used Eclipse some 20 years ago or whatever. It is absolutely non-intuitive to create a new project and add existing files to it.
Clicking around like a madman in the various menu options I find things like linking to an existing folders with a warning that Eclipse will try to delete everything in the folder if I click Next... (?)
I have created 4 projects now with the "Cretates a PHP project", and they all reside in my eclipse_workspace, Yet the project explorer says "There are no projects in your workspace ...".
This all is so infernally frustrating, I go back to my plain text editor with a PHP-extension.
It should really be the simplest of things in a programming IDE.
