Phing functionality in PhpStorm is provided through a dedicated Phing Build tool window.
In this section:
If the Phing support is not enabled in the project, open a Phing build file in the editor or select it
in the Project tool window, and then choose Add as Phing build file on the context menu of the selection.
If Phing is supported at the project level, choose on the main menu.
Open the Phing Build tool window.
Select the required build file in the list and click the Run button on the toolbar
or choose Run Build on the context menu of the selection.
