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 log-in program. There is a few configuration options like if you want to be notified if the user attempts to log-in a second time. The ipLogFile.txt file will need to have writable permissions in order for the program to write the users data to the logfile.
