How can the SQL syntax error related to the Kundennummer be resolved in the PHP code snippet for updating the Warenkorb?

The SQL syntax error related to the Kundennummer can be resolved by properly escaping the value of Kundennummer before inserting it into the SQL query. This can be achieved using prepared statements in PHP, which automatically handles escaping and sanitizing user input to prevent SQL injection attacks. 

// Assuming $kundennummer contains the Kundennummer value
// Assuming $warenkorb_id contains the Warenkorb ID value

// Establish a database connection
$pdo = new PDO("mysql:host=localhost;dbname=your_database", "username", "password");

// Prepare the SQL query using prepared statements
$stmt = $pdo->prepare("UPDATE Warenkorb SET Kundennummer = :kundennummer WHERE Warenkorb_ID = :warenkorb_id");

// Bind the parameters
$stmt->bindParam(':kundennummer', $kundennummer);
$stmt->bindParam(':warenkorb_id', $warenkorb_id);

// Execute the query
$stmt->execute();
