macOS Execute external app and return results to a function

[slooksterPSV]

I'm making a program, called STK WebEdit Lite, where you can edit and preview web pages, I want to be able to execute PHP so the user can see how the PHP is interacting with the web page. Is there a way I can execute the php command using Cocoa programming? I know there's a way to do it, but I can't remember how.

Use NSTask to spawn an external process. There is no special built in way for PHP.
