示例

use \Workerman\Worker;
use \Workerman\Connection\AsyncTcpConnection;

$task = new Worker();
// 进程启动时异步建立一个到www.baidu.com连接对象，并发送数据获取数据
$task->onWorkerStart = function($task)
{
    $connection_to_baidu = new AsyncTcpConnection('tcp://www.baidu.com:80');
    // 当连接建立成功时，发送http请求数据
    $connection_to_baidu->onConnect = function($connection_to_baidu)
    {
        echo "connect success\n";
        $connection_to_baidu->send("GET / HTTP/1.1\r\nHost: www.baidu.com\r\nConnection: keep-alive\r\n\r\n");
    };
    $connection_to_baidu->onMessage = function($connection_to_baidu, $http_buffer)
    {
        echo $http_buffer;
    };
    $connection_to_baidu->onClose = function($connection_to_baidu)
    {
        echo "connection closed\n";
    };
    $connection_to_baidu->onError = function($connection_to_baidu, $code, $msg)
    {
        echo "Error code:$code msg:$msg\n";
    };
    $connection_to_baidu->connect();
};
