Adding an include path

One of the software engineering principles says that components should be reusable, that is, the structure of the software should be modular. This is a practice accepted worldwide, but this adds an overhead to the translation (interpreter or compiler) to link the modules together by first finding them. PHP is no different.

How to do it...

You have the freedom to set this in PhpStorm. Go to Settings | PHP | Include Path. Select the new path. Click on Apply. Done! Take a look at the following screenshot, which illlustrates this point:

Tip

You should always make sure that you plan how to organize your files and folders beforehand so that a minimum number of include path settings are required.

If a folder is provided in the include path, it will be helpful in autocompletion for include(), require(), and so on.
