Yar_Concurrent_Client::loop

(PECL yar >= 1.0.0)

Yar_Concurrent_Client::loop — Send all calls

Description

public static boolean Yar_Concurrent_Client::loop ([ callable $callback [, callable $error_callback ]] )

Send all registed remote RPC calls.

Parameters

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.

Return Values

Examples

Example #1 Yar_Concurrent_Client::loop() example

<?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
?>

The above example will output something similar to:

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"
