Hello world

An example of a web server written with Swoole which responds 'Hello World':

<?php
$http = new swoole_http_server("127.0.0.1", 9501);

$http->on('start', function ($server) {
    echo "Swoole http server is started at http://127.0.0.1:9501\n";
});

$http->on('request', function ($request, $response) {
    $response->header("Content-Type", "text/plain");
    $response->end("Hello World\n");
});

$http->start();

To run the server, put the code into a file named server.php and execute it in the cli mode of php:

$ php server.php
$ curl http://127.0.0.1:9501/
