I know i'm the only person who uses PHPEd & Symfony, but here's a tip anyway...
How to add a Symfony command:

1. Menu: Tools->Settings
2. Go to Tools -> Integration
3. Click "Add Menu"
4. Enter "Symfony cc" in menu name
5. Select "Shell" from Execute with list
6. Enter php @ProjRoot@/symfony cc in command line
7. Select checkbox next to "Show this command in Workspace" group
8. Deselect "for files" checkbox
9. Select "for directories and projects"

Save and then try right-clicking on a project!
