How can the PHP code provided be optimized or improved for better performance in handling SOCKS requests and responses?

The PHP code can be optimized for better performance in handling SOCKS requests and responses by using asynchronous programming techniques, such as non-blocking I/O. This can be achieved by utilizing libraries like ReactPHP or Amp to handle multiple concurrent SOCKS requests efficiently. 

// Example of using ReactPHP library for handling SOCKS requests asynchronously

require 'vendor/autoload.php';

$loop = React\EventLoop\Factory::create();
$connector = new React\Socket\Connector($loop);

$socks = new Clue\React\Socks\Client($connector);

$socks->create('socks://127.0.0.1:1080')->then(function (React\Socket\ConnectionInterface $connection) {
    $connection->write("GET / HTTP/1.0\r\n\r\n");
    $connection->on('data', function ($data) {
        echo $data;
    });
});

$loop->run();
