一、安装 Yar

pecl install yar
pecl install msgpack

二、确保 php 加载 yar 模块
 

php -m

三、编写服务器端 Server.php ， 在浏览器打开 http://.../Server.php 可见API的介绍如下

<?phpclass API {public function some_method($parameter, $options = "foo") {$info = "welcome, {$parameter}, ".$_SERVER['REMOTE_ADDR'];return json_encode(array('res' => $info));}public function demo() {sleep(1);return "123";}
}

四、编写客户端 Client.php ， 编写完毕可 php Client.php 查看结果

<?php$client = new Yar_Client("http://.../Server.php");$client->SetOpt(YAR_OPT_CONNECT_TIMEOUT, 1000);// $client->SetOpt(YAR_OPT_HEADER, array("hd1: val"));$result = $client->some_method("panguangyu");print_r($result) // 会显示Server.php中some_method方法执行的结果

五、并发性测试 MultiClient.php ， 编写完毕可 php MultiClient.php 查看结果

<?phpfunction callback($retval, $callinfo) {echo "success\n";var_dump($retval);var_dump($callinfo);
}function error_callback($type, $error, $callinfo) {echo "error\n";error_log($error);
}Yar_Concurrent_Client::call("http://.../Server.php", "demo", array(), "callback", "error_callback");Yar_Concurrent_Client::call("http://.../Server.php", "demo", array(), "callback", "error_callback");Yar_Concurrent_Client::call("http://.../Server.php", "demo", array(), "callback", "error_callback");Yar_Concurrent_Client::loop();
