What are some potential pitfalls of using PHP for building a Content Management System, especially when it comes to updating database records?

One potential pitfall of using PHP for building a Content Management System is the risk of SQL injection attacks when updating database records. To prevent this, you should always use prepared statements with parameterized queries to sanitize user input and prevent malicious code injection. 

// Using prepared statements to update database records safely
$stmt = $pdo->prepare("UPDATE users SET username = :username WHERE id = :id");
$stmt->bindParam(':username', $username);
$stmt->bindParam(':id', $id);
$stmt->execute();
