Free-PHP

You can use this view only once PHP program along with your current PHP log-in program. This code will allow you to restrict access to a particular file. The user can view the resource only once within a pre-set amount of time. The username, password, date and the users IP address are written to a logfile. The code compares the username and password combinations for a match and determines if the alloted time limit has expired. If all is well the function returns back to your actual login script.
