This guide will take you step by step on how to create and use databases using CLI
1. Run the following command in the terminal:
$ mdb database init
2. Choose mysql8
3. You will be asked to create new user. Hit Enter to accept.
4. Provide username, password, database name and
description.
CLI will display your username, password, database name and connections string.
Note: Your final username and database name may differ from your inputs. MDB GO may add some characters to randomize username and database name.
5. Your database is ready to use.
<?php
$mysqli = new mysqli("mysql.db.mdbgo.com:3306","username","password","database_name");
// Check connection
if ($mysqli -> connect_errno) {
echo "Failed to connect to MySQL: " . $mysqli -> connect_error;
exit();
}
?>
const mysql = require('mysql');
const con = mysql.createConnection({
host: "mysql.db.mdbgo.com",
port: "3306",
user: "username",
password: "password"
});
con.connect(function(err) {
if (err) throw err;
console.log("Connected!");
});
Check following examples where you will find 3 different ways to connect to database using PHP using:
Each use case consists of sample code for:

1. In order to use it navigate to: phpmyadmin.mdbgo.com
2. Provide your username and password for the database you want to connect.
Note: You can check your username in your Databases panel. If you forget your password you can also reset it here.
