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"
