例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();
?>

例2 Access the server in borwser(GET request)

上の例の出力は、たとえば以下のようになります。

例3 Yar Client Example

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

/* call directly */
var_dump($client->add(1, 2));

/* call via call */
var_dump($client->call("add", array(3, 2)));


/* __add can not be called */
var_dump($client->_add(1, 2));
?>

上の例の出力は、たとえば以下のようになります。

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

例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(1, 2), "callback");
Yar_Concurrent_Client::call("http://example.com/operator.php", "sub", array(2, 1), "callback");
Yar_Concurrent_Client::call("http://example.com/operator.php", "mul", array(2, 2), "callback");

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

上の例の出力は、たとえば以下のようになります。

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