What are some potential pitfalls for beginners when trying to integrate a shop system into a website using PHP?

One potential pitfall for beginners when integrating a shop system into a website using PHP is not properly sanitizing user input, which can leave the website vulnerable to SQL injection attacks. To solve this issue, always use prepared statements when executing SQL queries to prevent malicious input from affecting the database. 

// Example of using prepared statements to sanitize user input
$stmt = $pdo->prepare('SELECT * FROM products WHERE id = :id');
$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$stmt->execute();
