How can one ensure a successful response reception when sending XML data via UDP in PHP?

When sending XML data via UDP in PHP, one way to ensure a successful response reception is to implement a timeout mechanism to handle cases where a response may not be received in a timely manner. This can be achieved by setting a timeout value for the socket connection and handling any potential timeout exceptions gracefully. 

<?php

// Create a UDP socket
$socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);

// Set a timeout value for the socket connection
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, array("sec" => 1, "usec" => 0));

// Send XML data
$xmlData = "<example><data>123</data></example>";
socket_sendto($socket, $xmlData, strlen($xmlData), 0, '127.0.0.1', 1234);

// Receive response
$from = '';
$port = 0;
socket_recvfrom($socket, $response, 1024, 0, $from, $port);

// Close the socket
socket_close($socket);

// Process the response
echo "Response received: " . $response;

?>
