Question

ReachPHP服务器。计算请求数量的代码：

$counter = 0;

$app = function ($request, $response) use ($counter){        
    $response->writeHead(200, array('Content-Type' => 'text/plain'));
    $response->end($counter);
    $counter++;
};

$loop = React\EventLoop\Factory::create();
$socket = new React\Socket\Server($loop);
$http = new React\Http\Server($socket, $loop);

$http->on('request', $app);
echo "Server running at http://127.0.0.1:1337\n";

$socket->listen(1337);
$loop->run();

对于每个请求，计数器保持为0，如何对服务器的所有请求使$ counter变量持久化？

只需要在$ counter之前输入＆amp; -sign以通过引用转移：

$counter = 0;

$app = function ($request, $response) use (&$counter){        
    $response->writeHead(200, array('Content-Type' => 'text/plain'));
    $response->end($counter);
    $counter++;
};

$loop = React\EventLoop\Factory::create();
$socket = new React\Socket\Server($loop);
$http = new React\Http\Server($socket, $loop);

$http->on('request', $app);
echo "Server running at http://127.0.0.1:1337\n";

$socket->listen(1337);
$loop->run();

傻傻的我......

如何在reactPHP服务器中保持状态？
