What are the potential security risks associated with using PHP for backend development in a hybrid app?

Potential security risks associated with using PHP for backend development in a hybrid app include SQL injection attacks, cross-site scripting (XSS) vulnerabilities, and insecure file uploads. To mitigate these risks, developers should sanitize user input, use parameterized queries for database operations, validate and sanitize data before processing it, and implement proper file upload validation and security measures. 

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