Run PHP shell

[dzedward]

I have a socket server php file that I need to be running at all times on my server.  Its an apache server running on OS X.  I see how I can do this with windows by creating a bat file and running the shell by command prompt, but how would I go about this on the Mac.  Remember I need this running at all times, without having to navigate to the php file in a web browser.  That way it will always be listening for connections on a certain port.  Any ideas?

Thank you.
