You can use this script along with your current log-in script. This script will allow you to restrict access to a particular file. The user can view the resource only once within a pre-set ammount of time. The username, password and date are written to a logfile. The script compares the username and password combonations 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 script. 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 (chmod 666) in order for the script to write the users data to the logfile.

PHPCoder is a web based front-end to the Turck MMCache encoding functions, which are similar to the Zend Encoder product.
PHPCoder enables you to encode your PHP scripts and applications into non reversible byte-code, thus preventing users of your programs from viewing or alterting the source code while having full functionality. Another excellent use for PHPCoder is to encode your applications PHP configuration files, that way someone viewing your source code does not see your databae login and password information.
In addition to encoding PHP scripts PHPCoder allows you to set restrictions on the encoded scripts, you can lock a script to a particular server IP address, server host name, visitor IP, or even place a time limit on the script so it will expire after x amount of time. PHP Coder also allows you to specify Text, HTML or PHP code that should be prepended and appended to each file before it is encoded, allowing you to easily and securely implement your own licensing scheme.
