What are some best practices for handling incoming connections and responses in a PHP SOCKS server?

When handling incoming connections and responses in a PHP SOCKS server, it is important to properly manage the socket connections, handle errors gracefully, and ensure that the server responds correctly to client requests. 

// Create a socket server
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_bind($socket, '0.0.0.0', 1080);
socket_listen($socket);

// Accept incoming connections
$client = socket_accept($socket);
if ($client === false) {
    // Handle error
    die("Error accepting connection");
}

// Read client request
$request = socket_read($client, 1024);
if ($request === false) {
    // Handle error
    die("Error reading request");
}

// Process client request
// (Code to handle SOCKS protocol logic)

// Send response back to client
$response = "OK";
socket_write($client, $response, strlen($response));

// Close client connection
socket_close($client);

// Close server socket
socket_close($socket);
