Content Root

Content is a set of roots that can belong to one of the following types:

• Files under a folder marked as Resource Root can be referenced relative to this folder.

  These roots are marked with the icon .

• Test Sources folders contain source files related to unit testing.

  These roots are marked with the icon .

• Excluded folders contain files and folders ignored by PhpStorm when indexing, searching, parsing, watching, etc. These roots are marked with the icon. Excluded roots are not visible to PhpStorm. Usually, one would like to exclude temporary build folders, generated output, logs, and other project output. Excluding the unnecessary paths is a good way to significantly improve performance.
