I\'m tempted by Automator.app\'s ability to create contextual services in Mac OS X Snow Leopard. I would like to create some keyboard accessible shortcuts to manipulate text
This is just a hack, but how about creating a python, or ruby or perl or bash script that calls php command-line interpreter with the php script you want to execute?
For instance in bash would be as simple as this:
#!/bin/bash
php myscript.php
Now save it, give it permission for execution:
chmod +x my_bash_script.sh
And voilá. Automator can now run the bash script, which calls the php script.
