Hello, I am new to PHP and programming in general and I am looking for some suggestions on how to implement some functionality I need for a website I am building.
I want to limit the amount of time a user is able to use a website based on information in a database. The website is a robotic observatory control website. Users buy time and are scheduled to use the observatory during certain times. I have built a MySQL database that contains schedule, privilege and user logon information. I have a front end PHP web page that uses this information to authenticate a user and then forward them to the observatory control page. Once they are at that page, I need to be able to limit the time they have access to the observatory control page. I am not sure how to implement a process that wraps around the observatory control page and will boot a user once their time expires or they log off or they reach the end of their scheduled time. I know this is a bit vague but I'm not sure where to begin. How would one allow a user the full functions of a given web page and then boot them from that page once some criteria are met? A PHP "do while" loop? A completely separate background application that monitors the exit criteria and then disconnects the user from the webpage? Thanks, Dave
