<?php
function callback($ret, $callinfo) {
echo $callinfo['method'] , " result: ", $ret , "\n";
}
/* register async call to remote services */
Yar_Concurrent_Client::call("http://example.com/operator.php", "add", array(1, 2), "callback");
Yar_Concurrent_Client::call("http://example.com/operator.php", "sub", array(2, 1), "callback");
Yar_Concurrent_Client::call("http://example.com/operator.php", "mul", array(2, 2), "callback");
/* sent all request and wait for response */
Yar_Concurrent_Client::loop();
?>
O exemplo acima produzirá
algo semelhante a:
mul result: 4
sub result: 1
add result: 3
