Yii2

server.php

<?php
require_once __DIR__ . '/vendor/autoload.php';

use Adapterman\Adapterman;
use Workerman\Worker;
use Workerman\Lib\Timer;

Adapterman::init();

require __DIR__.'/start.php';

$http_worker                = new Worker('http://0.0.0.0:8080');
$http_worker->count         = (int) shell_exec('nproc') * 4;
$http_worker->name          = 'AdapterMan-Yii2';

$http_worker->onWorkerStart = static function () {
    WorkerTimer::init();
};

$http_worker->onMessage = static function ($connection) {

    $_SERVER['SCRIPT_FILENAME'] = '/app/index.php'; // fix
    $_SERVER['SCRIPT_NAME'] = '/index.php'; // fix
    header(WorkerTimer::$date); // optional, the Date header is added automatically with Nginx or any other web server
    $connection->send(
        run()
    );
};

class WorkerTimer
{
    public static $date;

    public static function init()
    {
        self::$date = 'Date: '.gmdate('D, d M Y H:i:s').' GMT';
        Timer::add(1, function() {
            WorkerTimer::$date = 'Date: '.gmdate('D, d M Y H:i:s').' GMT';
        });
    }
}

Worker::runAll();

start.php

<?php

define('YII_ENABLE_ERROR_HANDLER', false);

require __DIR__ . '/vendor/yiisoft/yii2/Yii.php';

// Change to your config
$config = [
    'id' => 'benchmark',
    'basePath' => __DIR__ . '/app',

        'urlManager' => function() {
            return new yii\web\UrlManager([
                'enablePrettyUrl' => true,
            ]);
        },

        'request' => function() { return new yii\web\Request(); },
        'response' => function() { return new yii\web\Response(); },
    ],
];

//(new  yii\web\Application($config))->run();

function run()
{
    global $config;
    ob_start();
    (new yii\web\Application($config))->run();
    return ob_get_clean();
}

You can check it in the benchmark, I used the same code that with php-fpm. There I used the same index.php, and only comment the (new yii\web\Application($config))->run(); ~And 1 line changed in the core. vendor/yiisoft/yii2/web/Response.php
(headers_sent($file, $line)) -> (headers_sent())~ (Fixed)

Perhaps will be good to add an issue for this line in Yii2 repo. And perhaps also to don't need to hardcode the $_SERVER, that it's always the same file.

$_SERVER['SCRIPT_FILENAME'] = '/app/index.php'; // fix
$_SERVER['SCRIPT_NAME'] = '/index.php'; // fix

Yii2 bechmark results with php-fpm and Adapterman:

Commit f1f5b3c, fix the headers_sent() problem with Yii2. So it isn't necessary to touch the Yii2 Response in vendor dir.
