What are some potential challenges or difficulties in self-programming a CMS using PHP for website management?

One potential challenge in self-programming a CMS using PHP is ensuring security measures are in place to prevent vulnerabilities such as SQL injection or cross-site scripting attacks. To address this, it is important to sanitize user input and use prepared statements when interacting with the database. 

// Sanitize user input
$username = filter_var($_POST['username'], FILTER_SANITIZE_STRING);
$password = filter_var($_POST['password'], FILTER_SANITIZE_STRING);

// Prepare and execute a SQL statement using prepared statements
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username AND password = :password");
$stmt->bindParam(':username', $username);
$stmt->bindParam(':password', $password);
$stmt->execute();
