How to write replacement information in mySQL if no value is post | PDO mySQL : I have the following PDO script that looks for the values.

    $stmt = $pdo->prepare( ' INSERT INTO `table1` (`person`, `player`, `card)
        
    VALUES (:person, :player, :card) ' );

        
    $stmt->execute([
        'person' => $_POST['person'],
        'player' => $_POST['player'],
        'card' => $_POST['card']
    ]);


If the value for player for example is not posted, the value should automatically write the value `Nothing`. 

How can this be implemented using mySQL and PDO?
