What are the potential pitfalls of using PHP to create a navigation menu?

One potential pitfall of using PHP to create a navigation menu is the risk of security vulnerabilities such as SQL injection or cross-site scripting if user input is not properly sanitized. To mitigate this risk, always validate and sanitize user input before using it in your PHP code. 

// Example of sanitizing user input in PHP
$user_input = $_GET['user_input'];
$sanitized_input = filter_var($user_input, FILTER_SANITIZE_STRING);
