swoole http server 简单程序生成的opcode
代码如下
<?php
$http = new swoole_http_server("0.0.0.0", 8080);
$http->set(array(
'worker_num' => 1
));
$http->on('request', function ($request, $response) {
//var_dump($request->get, $request->post);
$response->header("Connection: close","Content-Type", "text/html; charset=utf-8");
$response->end("<h1>Hello Swoole. #".rand(1000, 9999)."</h1>");
});
$http->on('close', function ($serv, $fd) {
echo "Client: Close{$fd}.\n";
});
$http->start();
查看opcode
php -dvld.active=1 swoole_http_server.php
当然 dvld 扩展需要提前安装
