Example of php asynchronous multi-thread swoole usage

This article mainly introduces the usage of php asynchronous multi-thread swoole and describes the asynchronous multi-thread feature of swoole in the form of an instance. if you need it, refer to the following example to illustrate the usage of php asynchronous multi-thread swoole. Share it with you for your reference. The specific analysis is as follows:

Swoole redefined the high-performance network communication framework of the PHP language and provided the asynchronous multi-thread service of the PHP language. the following example can prove this function.

In general, Swoole provides PHP asynchronous multi-thread server, asynchronous TCP/UDP network client, asynchronous MySQL, database connection pool, AsyncTask, message queue, millisecond timer, asynchronous file read/write, asynchronous DNS query.

Swoole has heard of it before. the server used to play games is simply an artifact... Today, I felt a little bit, set up the environment in ubuntu, and tested it.

The specific test code is as follows:

The code is as follows:

<? Php
Class page extends Controller
{
Function index ()
{
$ Data = createModel ('userinfo')-> get (12)-> get ();
$ This-> swoole-> tpl-> assign ('data', $ data );
$ Html = $ this-> swoole-> tpl-> fetch('test.html ');
$ Time = $ this-> showTime ();
Return $ html. $ time;
}
}
Shell
AB-c 100-n 1000-k http: // 127.0.0.1/index/

Apache has such a high efficiency, and it will be useful in the future.

I hope this article will help you with PHP programming.
