Use this dialog box to configure content roots of a project.
|Add Content Root||Click this button and select a new content root folder in the dialog that opens.|

|Tests||Click this button to mark the selected folder as a test root.|
Click this button to mark the selected folder as the root for namespaces used in your project.
Based on this setting, PhpStorm suggests you the proper folder name when you want to create a new namespace under another parent namespace during creation or moving a PHP class, that is, when you are actually creating or moving a PHP class to a non-existing namespace under another parent namespace. If no Sources folder is specified, you will have to type the proper folder manually.
|Excluded||Click this button to mark the selected folder as excluded so PhpStorm ignores it during indexing, parsing, and code completion.|
|Resource Root||Click this button to enable PhpStorm to complete relative paths to resources under the selected folder.|
|Include||Click this button to have the exclusion mark removed from the selected excluded content root.|
