Redefines all MySQL functions as mysqli (for PHP>=7)
For PHP versions greater or equal to 7, this script serves as a workaround and replaces all mysql functions with their mysqli equivalents. Vulnerability issues may arise, so it is advisable to use the recommended more recent mysqli-functions instead. You can update old code by adding this line at the beginning of it if you're confident it won't put your server at risk.
Use:
Download and include the file at the top of your PHP script
include_once('mysql_redefine.php');
