If you sell digital products online such as software programs, games, phone PIN numbers and so on, then PHP-KeyCodes can be a useful application to install on your web site. It requires a web server running PHP and access to a MySQL database. It is easy to install with a one page install script and upload of files to your server.
If you have a requirement to sell codes on line then this is a better method than using someone else’s web site as you do not have to pay them any fees.
Using a license system for your software program helps to prevent fraud and allows you to send free trial versions to customers. The key codes are loaded into the PHP-KeyCodes web site administration interface so that they are automatically sent whenever there is a purchase using PayPal.
The system will also send you an email when it is getting low on licence keys.
The usual way to use PHP-KeyCodes is to enter the codes into the admin area so that the next code in the list is taken and sent when there is a purchase.
The PHP script has been written in such a way as to allow you to modify the program to cover other situations. So for example you may have codes in a text file that you want to upload to the server. You could modify the code to use such a text file. You could even have code that generates a key code depending on the user name or email address.
If you have particular requirements, then we would be willing to customize the code for you.
