Let's talk about how to use php swoole to build a high-performance server environment

With the continuous development of computer technology, today's server frameworks have become more and more complex. Have you ever encountered problems such as large visits and slow response speed? php swoole is an emerging server framework that can use the PHP language to build high-performance web servers and clients. In this article, we will introduce how to use php swoole to build a high-performance server environment.

1. Environment preparation

1. Install PHP

Before this, we need to install PHP. We can use the command line to install:

sudo apt-get install php7.0

The following results indicate that the installation is successful:

2. Install the PECL extension

Then you should install the PECL extension, PECL is the PHP Extension Community Library The abbreviation of PECL is a community of PHP extension libraries that can install and manage PHP extensions through PECL.

Execute the following command:

sudo apt-get install php7.0-dev

The following results indicate successful installation:

3. Install Swoole

Swoole is the core extension of phpswoole, which can use high-performance asynchronous network IO and HTTP server functions in PHP.

Execute the following command:

sudo pecl install swoole

The following results indicate successful installation:

2. Code implementation

In After the environment is prepared, we can start implementing the code.

Before we start, we need to create a directory first. Suppose we call it swoole_server and create a file in it. Suppose the file is named server.php and the code is as follows:

<?php
$server = new Swoole\Server("127.0.0.1", 9501);

$server->on('connect', function ($server, $fd){
    echo "Client:Connect.\n";
});

$server->on('receive', function ($ser, $fd, $from_id, $data){
    $ser->send($fd, "Server: ".$data);
});

$server->on('close', function ($ser, $fd){
    echo "Client: Close.\n";
});

$server->start();
?>

Above The code implements a simple server that listens to port 9501 at the 127.0.0.1 address. When the client connects to this server, the server will print "Client:Connect.", and when the client sends a message, the server will respond. Server:", and when the client closes, the server prints "Client:Close.".

3. Start the server

After completing the above code, we need to save it to the server.php file, and then use the command line to start the server:

php server. php

The following results indicate that the server started successfully:

4. Test the server

We can use the telnet tool to test the server, just enter the following command in the terminal:

telnet 127.0.0.1 9501

The following results indicate a successful test:

5. Conclusion

Through the introduction of this article, we can see that using phpswoole to build The server environment is still very simple. With just a few preparation steps and some simple code implementation, you can build a high-performance server. Hope this helps everyone, thank you!
