What potential pitfalls should be considered when using PHP to create new pages?

One potential pitfall when using PHP to create new pages is the risk of SQL injection attacks if user input is not properly sanitized. To prevent this, always use prepared statements or parameterized queries when interacting with a database to avoid malicious SQL injection attempts. 

// Example of using prepared statements to prevent SQL injection
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = ?");
$stmt->execute([$username]);
