How to load php DS namespace in PhpStorm
phpstorm
Solution
You need stub files in order for PhpStorm to understand what DS (a PHP extension written in C) offers (classes/functions/etc).
Stub file is basically a PHP version of that -- just "declaration/documentation" part -- e.g. function declarations but with empty bodies. You can either make your own ... or find some existing ones (if somebody else did it already, of course).
A bit more on stub files in general:

So .. basically what you need is php-ds/polyfill -- "You should also include the polyfill in your project for compatibility and IDE integration" .
IDE will read such files and will understand what real DS extension has to offer/what it does (type of parameters/returns/etc).
Problem
I have installed php-ds extension as shown here. But I am unable to Load the DS namespace in PhpStorm. How can I do this?
