Can you build a relational database using WAMP?

Thanks for the help, it has worked, the trouble now is i have created a page that should add a meal, but the code does not seem to work all it does is refreshes the page. which to me suggests it is doing what it's supposed to but no data is being inserted in the database.

<?php
$dbhost = 'localhost';
    $dbuser = 'root';
    $dbpass = '';
    $db = 'test';
    $conn = mysqli_connect($dbhost, $dbuser, $dbpass, $db);
    if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }

if ($_SERVER['REQUEST_METHOD'] == 'POST')
    {
    //$MealID = $_POST['MealID'];
    $Meal = $_POST['Meal'];
    $Price = $_POST['MealPrice'];

    if ($conn) {

    $SQL = "INSERT INTO meal (Meal, Price) VALUES ('" . $Meal . "', '" . $Price . "')";

    $result = mysqli_query($conn, $SQL);
    mysqli_close($conn);
    }
    else {

    print "Database NOT Found ";
    mysqli_close($conn);
    }
    }

?>
