(PECL yar >= 1.0.0)

Yar_Concurrent_Client::loop — Send all calls

### 説明

public static function Yar_Concurrent_Client::loop(callable `$callback` = ?, callable `$error_callback` = ?): bool

Send all registered remote RPC calls.

### パラメータ

`callback`

  If this callback is set, then Yar will call this callback after all calls are sent and before any response return, with a $callinfo NULL.

  Then, if user didn't specify callback when registering concurrent call, this callback will be used to handle response, otherwise, the callback specified while registering will be used.

`error_callback`

  If this callback is set, then Yar will call this callback while error occurred.

### 例

例1 Yar_Concurrent_Client::loop() example

    <?php
    function callback($retval, $callinfo) {
         if ($callinfo == NULL) {
            echo "Now, all requests are sent, and no 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
    ?>

上の例の出力は、 たとえば以下のようになります。

    Now, all requests are sent, and no 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"
