Convert Adobe Coldfusion Code to PHP

A very small project to convert existing Adobe Coldfusion cfml code into PHP code and to remodel the application slightly to remove unecessary functionality. The current code is only about 800 lines long. The current code retrieves style information from an external site (via CFHTTP) which is no longer needed. The intention is that this code will be able to sit on an existing PHP based site. The application simply checks a serial number against a very simple database table structure to determine if the serial number is valid or not.
