    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。

    Yar Server Info

    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

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

    /* 注册一个异步调用 */
    Yar_Concurrent_Client::call("http://example.com/operator.php", "add", array(1, 2), "callback");
    /* 发送所有注册的调用, 等待返回, 返回后Yar会调用callback回掉函数 */
    Yar_Concurrent_Client::loop();
    /* 重置call ,否则上面的call会调用*/
    Yar_Concurrent_Client::reset();
    Yar_Concurrent_Client::call("http://example.com/operator.php", "sub", array(2, 1), "callback");
    Yar_Concurrent_Client::loop();
