As the web and free sources don’t have too much to offer for the moment, I have started development. phpMyTicket has been tested for these purposes, and (without using any of its specific ideas) it is still in a very buggy state, probably because of its base complexity. Starting off small might solve this problem.
Let’s get to it then.
Remember, phpReservation is only in Alpha stage, so don’t expect any release soon. If anyone is interested, talk in the comments to get developing!
