What is the best way to get a configuration variable in PHP

Question

Each server (Dev, QA, Prod) has a different IP address and URL. I would like to write code so that it can pull that information (the URL for the particular server I am running the code on) from a configuration file and store it in a variable.

Preferably I would like to avoid having to read the information from a file on subsequent requests since the information should not be changing often.

What is the best way to accomplish this?

Use the $_SERVER array to get the current server details

Specifically, $_SERVER['SERVER_ADDR'] and $_SERVER['SERVER_NAME'] (IP + hostname of the host/virtual host the script's running in).
