For developers who are using Tom Harrington’s original PHP-based backend, you should know that the last compatible PHP version that works with this script, 5.6 is now end of life. Since the script uses the out of date mysql_* methods and PHP 7 removed this entirely, the script will not work. Now, I updated the script to use mysqli_* so it can run on PHP 7 in addition to PHP 5.x. You can get it here.
I will be making future improvements such as refactoring the script and update it to use prepared statements for additional security against SQL Injection.
