This is something I actually do understand. I was wondering if the code running on the server had to query the server for the information every time a $_SERVER var was referenced, but like Daniel explained, the contents of the $_SERVER array are populated at runtime and so no further "hey server, what version of apache are you running?" questions need to be asked of it.
