PS! After establishing connection to mySQL server and then performing CRUD then it would be a good practice to CLOSE the connection like this:
mysqli_close($conn);
Connect to MySQL DATABASE using PHP.
define('HOSTNAME', 'localhost');
define('USERNAME', 'root');
define('PASSWORD', '');
define('DB_NAME', 'crud-app');
// $conn = mysqli_connect('localhost', 'root', '', 'crud-app');
$conn = mysqli_connect('HOSTNAME', 'USERNAME', 'PASSWORD', 'DB_NAME');
if ($conn) {
echo 'success!!!';
} else {
die ("Connection lost!!!" . mysqli_connect_error($conn));
}
// this CLOSE function is not required with PHP but it would be a good practice.
mysqli_close($conn);
