PhpStorm composer manage dependencies
If you have a project which has already the composer.json file and you want to add some php packages to it you can find manage dependencies menu here:
Then a Manage Composer Dependencies window will appear and we can search and add what package we want and determine the specific version we need.
This feature is in PhpStorm since 2017 ( read here )
Also we can activate command line tool in the project.
In the editor preferences (setting) (cmd ,) search this : command line
Then click on the + sign
Then press double ^ (control key) to appear the window for “run anything” and then type and execute the commands. To disappear you just need again press double ^.
