PhpStorm 2016.3 Help

Opening Multiple Projects

On this page:


PhpStorm allows you to work with several projects simultaneously. So doing, PhpStorm suggests the following options:

  • Each project is opened in its own window. The projects are independent, and cannot share information, except for the Clipboard operations. All the projects run in the same instance of PhpStorm and use the same memory space.
  • A newly opened project shares the same window as the already opened one. So doing, the project that has already been opened, is considered the primary project, and is always shown first in the Project tool window. All the other projects are added to the primary project.

    Symbols from the added projects are visible from the primary one, but not vice versa.

    Some settings ( content roots) can be configured separately for each project.


Make sure that one of the options Open project in a new window or Confirm window to open project in in the System Settings page of the Settings/Preferences dialog is selected.

Opening multiple projects

To open multiple projects, follow these steps

  1. Open a project, while another one is already opened. PhpStorm prompts you to select whether you want to open the project in a new window, or reuse the existing window.
  2. Do one of the following:
    • Click Open in new window button to leave the current project in its window and open the new one in a separate window.
    • Click Open in current window, and select the check box Add to currently opened projects.
      The new project opens in the project tree, and adds to the currently opened project. So doing, the project that has already been opened, is the primary project.
