例1 Yar_Concurrent_Client::call() example

<?php
function callback($retval, $callinfo) {
     var_dump($retval);
}

function error_callback($type, $error, $callinfo) {
    error_log($error);
}

Yar_Concurrent_Client::call("http://host/api/", "some_method", array("parameters"), "callback");
Yar_Concurrent_Client::call("http://host/api/", "some_method", array("parameters"));   // if the callback is not specificed,
