How can developers ensure that their PHP CMS remains secure and protected against vulnerabilities?

Developers can ensure that their PHP CMS remains secure and protected against vulnerabilities by regularly updating their CMS software, plugins, and themes to the latest versions, implementing secure coding practices, using secure hosting services, and regularly conducting security audits and vulnerability assessments. 

// Example of implementing secure coding practices in PHP CMS

// Use prepared statements to prevent SQL injection
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
$stmt->execute(['username' => $username]);
$user = $stmt->fetch();

// Sanitize user input to prevent XSS attacks
$clean_input = htmlspecialchars($_POST['input'], ENT_QUOTES, 'UTF-8');

// Validate and sanitize file uploads to prevent malicious file uploads
if ($_FILES['file']['error'] === UPLOAD_ERR_OK) {
    $file_name = basename($_FILES['file']['name']);
    $file_path = 'uploads/' . $file_name;
    move_uploaded_file($_FILES['file']['tmp_name'], $file_path);
}
