How do I get the *list*of IP addresses registered on my server?

How do I get the listof IP addresses registered on my server?

I need a way for PHP to be able to detect the list of IP addresses that are registered on the server's network interface.

The project I'm working on runs on both Mac, Windows, and some other linux distros. Does anybody have a php function that can magically return an array that contains each of the IP addresses on the server where the script ran?

Thank you!
