Yar_Concurrent_Client::loop — Enviar todas las llamadas
$callback
[, callable $error_callback
]] )Envía todas las llamadas RPC remotas registradas.
callbackSi se establece esta retrollamada, Yar la invocará después de haber enviado todas las llamadas y antes de cualquier respuesta, con un $callinfo NULL.
Entonces, si un usuario no especifica la retrollamada al registrar una llamada concurretne, esta retrollamada se utilizará para manejar la resupesta, o si no, se utilizará la retrollamada especificada durante el registro.
error_callbackSi se establece esta retrollamada, Yar la invocará cuando suceda un error.
Ejemplo #1 Ejemplo de Yar_Concurrent_Client::loop()
<?php
function callback($retval, $callinfo) {
if ($callinfo == NULL) {
echo "Now, all requests are sent, and no any response available\n";
} else {
echo "This is a remote call response, the method name is", $callinfo["method"],
". calling sequence is " , $callinfo["sequence"] , "\n";
var_dump($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,
// callback in loop will be used
Yar_Concurrent_Client::call("http://host/api/", "some_method", array("parameters"), "callback", NULL, array(YAR_OPT_PACKAGER => "json"));
//this server accept json packager
Yar_Concurrent_Client::call("http://host/api/", "some_method", array("parameters"), "callback", NULL, array(YAR_OPT_TIMEOUT=>1));
//custom timeout
Yar_Concurrent_Client::loop("callback", "error_callback"); //send the requests,
//the error_callback is optional
?>
El resultado del ejemplo sería algo similar a:
Now, all requests are sent, and no any response available This is a remote call response, the method name issome_method. calling sequence is 4 string(11) "some_method" This is a remote call response, the method name issome_method. calling sequence is 1 string(11) "some_method" This is a remote call response, the method name issome_method. calling sequence is 2 string(11) "some_method" This is a remote call response, the method name issome_method. calling sequence is 3 string(11) "some_method"
