What are the differences between access control and SSL in PHP?

Access control in PHP involves setting permissions and restrictions on who can access certain resources or perform certain actions within a web application. SSL (Secure Sockets Layer) in PHP, on the other hand, is a protocol that ensures secure communication between a client and a server by encrypting data transmitted over the internet. While access control focuses on managing user permissions, SSL focuses on securing data transmission.

// Access control example
if($user->isAdmin()) {
    // Allow access to admin-only resources
} else {
    // Redirect or deny access
}

// SSL example
// Enable SSL for secure communication
$ssl_enabled = true;
if($ssl_enabled) {
    // Set up SSL configuration
    // This can be done in the server configuration or using PHP functions like stream_socket_enable_crypto()
}
