How can one efficiently send multiple datagrams to a server within a specific time frame using PHP?

To efficiently send multiple datagrams to a server within a specific time frame using PHP, you can utilize the `socket_create` and `socket_sendto` functions to create a UDP socket and send datagrams to the server. By setting a timeout for each send operation and using a loop to send multiple datagrams, you can achieve the desired behavior. 

<?php

$serverAddress = 'udp://127.0.0.1';
$serverPort = 1234;
$timeout = 1; // Timeout in seconds
$numDatagrams = 10; // Number of datagrams to send

$socket = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);

for ($i = 0; $i < $numDatagrams; $i++) {
    $data = "Datagram " . ($i + 1);
    socket_sendto($socket, $data, strlen($data), 0, $serverAddress, $serverPort);
    
    if (socket_select($r = [$socket], $w = [], $e = [], $timeout) === 0) {
        echo "Timeout occurred while sending datagram $i\n";
    } else {
        echo "Datagram $i sent successfully\n";
    }
}

socket_close($socket);

?>
