What are some common pitfalls to avoid when creating a "Sprungmenü" in PHP?

One common pitfall to avoid when creating a "Sprungmenü" in PHP is not properly sanitizing user input, which can lead to security vulnerabilities such as SQL injection attacks. To prevent this, always use prepared statements or parameterized queries when interacting with a database to ensure that user input is properly escaped. 

// Example of using prepared statements to prevent SQL injection

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

// Prepare SQL statement with placeholders
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");

// Bind parameters and execute query
$stmt->bindParam(':username', $_POST['username']);
$stmt->execute();

// Fetch results
$results = $stmt->fetchAll();
