How can developers ensure secure authorization practices in PHP applications?

Developers can ensure secure authorization practices in PHP applications by implementing role-based access control, validating user input to prevent SQL injection attacks, and using secure authentication methods like hashing passwords. Additionally, developers should regularly update their PHP version and libraries to patch any security vulnerabilities. 

// Example of implementing role-based access control in PHP

// Check if user has the necessary role to access a specific page
function checkUserRole($requiredRole) {
    if ($_SESSION['role'] !== $requiredRole) {
        header("HTTP/1.1 401 Unauthorized");
        exit();
    }
}

// Example usage
checkUserRole('admin');
