Example #1 Yar Server Example

<?php

/* assume this page can be accessed by http://example.com/operator.php */

class Operator {

    
/**
     * Add two operands
     * @param interge 
     * @return interge
     */
    
public function add($a$b) {
        return 
$this->_add($a$b);
    }

    
/**
     * Sub 
     */
    
public function sub($a$b) {
        return 
$a $b;
    }

    
/**
     * Mul
     */
    
public function mul($a$b) {
        return 
$a $b;
    }

    
/**
     * Protected methods will not be exposed
     * @param interge 
     * @return interge
     */
    
protected function _add($a$b) {
        return 
$a $b;
    }
}

$server = new Yar_Server(new Operator());
$server->handle();
?>

Example #2 Access the server in borwser(GET request)

Yar Server Info

Example #3 Yar Client Example

<?php
$client 
= new yar_client("http://example.com/operator.php");

/* call directly */
var_dump($client->add(12));

/* call via call */
var_dump($client->call("add", array(32)));


/* __add can not be called */
var_dump($client->_add(12));
?>

The above example will output something similar to:

int(3)
int(5)
PHP Fatal error:  Uncaught exception 'Yar_Server_Exception' with message 'call to api Operator::_add() failed' in *

Example #4 Yar Concurrent Client Example

<?php
function callback($ret$callinfo) {
    echo 
$callinfo['method'] , " result: "$ret "\n";
}

/* register async call to remote services */
Yar_Concurrent_Client::call("http://example.com/operator.php""add", array(12), "callback");
Yar_Concurrent_Client::call("http://example.com/operator.php""sub", array(21), "callback");
Yar_Concurrent_Client::call("http://example.com/operator.php""mul", array(22), "callback");

/* sent all request and wait for response */
Yar_Concurrent_Client::loop();
?>

The above example will output something similar to:

mul result: 4
sub result: 1
add result: 3
