How can PHP code be optimized to accurately display server status using UDP instead of TCP?

Using UDP instead of TCP can optimize PHP code for accurately displaying server status by reducing the overhead associated with establishing and maintaining a TCP connection. UDP allows for faster transmission of data as it does not require a handshake process like TCP. To implement this in PHP, you can use the socket functions to create a UDP socket and send a message to the server to retrieve its status. 

<?php
$serverAddress = 'udp://127.0.0.1';
$serverPort = 1234;

$socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
if (!$socket) {
    echo "Error creating socket: " . socket_last_error();
}

$message = "GET_STATUS";
socket_sendto($socket, $message, strlen($message), 0, $serverAddress, $serverPort);

$buf = '';
socket_recvfrom($socket, $buf, 1024, 0, $serverAddress, $serverPort);
echo "Server status: " . $buf;

socket_close($socket);
?>
