Configuring Include Paths
Include paths are used for code completion and reference resolution in some functions/methods that use file paths as arguments
You also need to configure PEAR as an include path to run the PHPUnit test framework from it
when the Load from include path option is chosen on the PHPUnit page of the Settings / Preferences Dialog.
To configure include paths:
- Open the Settings / Preferences Dialog by pressing Ctrl+Alt+S or by choosing for Windows and Linux or for OS X, and click PHP under Languages&Frameworks.
- In the PHP page that opens, click the Update include paths button.
- In the Include paths area, that becomes available upon pressing the Update include paths button, configure the list of include paths.
