What are some common pitfalls to avoid when trying to implement dynamic styling using PHP and MySQL for web development?

One common pitfall to avoid when implementing dynamic styling using PHP and MySQL is not properly sanitizing user input. This can lead to security vulnerabilities such as SQL injection attacks. To prevent this, always use prepared statements when querying the database to ensure that user input is properly escaped. 

// Example of using prepared statements to prevent SQL injection

// Assuming $db is the database connection
$stmt = $db->prepare("SELECT * FROM users WHERE username = ?");
$stmt->bind_param("s", $username);
$username = $_POST['username'];
$stmt->execute();
$result = $stmt->get_result();

// Use the $result to dynamically generate styles
