In what scenarios can setting up a TCP listener on a different port improve connection speed and prevent connection timeouts in PHP server-client communication?

Setting up a TCP listener on a different port can improve connection speed and prevent connection timeouts in PHP server-client communication when the default port (e.g., port 80 for HTTP) is congested or experiencing high traffic. By using a different port, you can ensure that your PHP server-client communication has a dedicated channel for faster and more reliable data transfer. 

<?php
// Server side code
$server = stream_socket_server("tcp://127.0.0.1:8888", $errno, $errstr);

if (!$server) {
    die("Error creating server: $errstr");
}

$client = stream_socket_accept($server);

// Handle client communication
fwrite($client, "Hello, client!");
fclose($client);

fclose($server);
?>
