PHP asynchronous multi-threaded swoole usage example

The example in this article describes the usage of php asynchronous multi-threaded swoole. Share it with everyone for your reference. The specific analysis is as follows:

swoole redefines the high-performance network communication framework of PHP language and provides asynchronous multi-threaded services of PHP language. The following example can confirm this function.

Generally speaking, Swoole provides asynchronous multi-threaded server in PHP language, asynchronous TCP/UDP network client, asynchronous MySQL, database connection pool, AsyncTask, message queue, millisecond timer, asynchronous file reading and writing, asynchronous DNS query.

Swoole has been heard before, and it is an artifact when used as a game server... I experienced it a little today, built an environment under ubuntu, and tested it

The specific test code is as follows:

<?php
class page extends Controller
{
    function index()
    {
        $data = createModel(&#39;UserInfo&#39;)->get(12)->get();
        $this->swoole->tpl->assign(&#39;data&#39;,$data);
        $html = $this->swoole->tpl->fetch(&#39;test.html&#39;);
        $time = $this->showTime();
        return $html.$time;
    }
}
shell
ab -c 100 -n 1000 -k http://127.0.0.1/index/

Apache can actually have such good efficiency, keep a claw. It will be useful in the future.

I hope this article will be helpful to everyone’s PHP programming design.
