Edit Project Path Mappings Dialog
The dialog opens when you configure a remote interpreter accessible through SFTP, Vagrant, or Docker, and click next to the Path mappings field on the PHP page of the Settings/Preferences dialog (Ctrl+Alt+S).
The mappings are automatically retrieved from the corresponding SFTP deployment configuration, Vagrantfile, or Dockerfile, and listed in the dialog. These mappings are read-only.
To add a custom mapping, click and specify the path in the project and the corresponding path on the remote runtime environment in the Local Path and Remote Path fields respectively. Type the paths manually or click and select the relevant files or folders in the dialog that opens.
To remove a custom mapping, select it in the list and click .
