User:Allen4names/Random Archive Query

I have created a PHP script that should be given the file name RandomArchiveQuery.php. Preliminary tests of this script have been done but you may want to have someone with more experience look this over and make changes. Configuration variable have been included so that common changes can be made quickly and easily as shown in the script below.
