$username = "username"; 
$password = "password"; 
$dbname = "myDB"; 

// Create connection 
$conn = new mysqli($servername, $username, $password, $dbname); 
// Check connection 
if ($conn->connect_error) { 
    die("Connection failed: " . $conn->connect_error); 
} 

$sql = "UPDATE MyGuests SET lastname='Doe' WHERE id=2"; 

if ($conn->query($sql) === TRUE) { 
    // if all ok, redirecting 
    header("Location: http://example.com/myOtherPage.php"); 
    die(); 
} else { 
    echo "Error updating record: " . $conn->error;
