What are some common pitfalls to avoid when using PHP for creating a rating script?

One common pitfall when creating a rating script in PHP is not properly sanitizing user input, which can lead to security vulnerabilities such as SQL injection attacks. To avoid this, always use prepared statements when interacting with the database to prevent malicious code injection. 

// Example of using prepared statements to sanitize user input in PHP
$rating = $_POST['rating'];

// Prepare a SQL statement
$stmt = $pdo->prepare("INSERT INTO ratings (rating) VALUES (:rating)");

// Bind the parameter and execute the statement
$stmt->bindParam(':rating', $rating);
$stmt->execute();
