First of all you need to set up a web server on your machine. That means you need Apache and MySQL service installed.
After you have these requirements, you have to download the test_server.sql and insert its values in your MySQL.
Next, you need to EDIT sql.php file in the second (2) line and change: ( $connection = mysqli_connect('IP','username','password','test_server'); )
1.) IP --> your servers IP, if it`s local then 127.0.0.1
2.) Username --> your MySQL username
3.) Password --> your MYSQL password
4.) Dont change test_server, it`s the database you installed previously
If everything is OK, then you will have ready your dummy site for testing my SQL Injection tool.
