How to use Workerman function in PHP

Workerman is a powerful and easy-to-use PHP framework that provides an easy way to create high-performance web applications. If you want to know how to use the Workerman function in PHP, this article will provide you with detailed guidance.

1. Install Workerman

First, you need to install Workerman. You can download the latest version of Workerman on the official website (http://www.workerman.net). Once the download is complete, unzip and copy the Workerman framework into your PHP project.

2. Introduce Workerman

Introduce the Workerman framework into your PHP code. You can import it in the following way:

require_once '/path/to/Workerman/Autoloader.php';

Replace /path/to accordingly with the path to the directory where the framework is located. This code allows you to use all Workerman classes.

3. Create a Workerman application

First, create a new PHP file, such as index.php. In this file, you need to define a new Workerman application. Here is a simple example:

use WorkermanWorker;

$worker = new Worker("websocket://127.0.0.1:8000");

$worker->onConnect = function($connection)
{
    echo "New Connection
";
};

$worker->onMessage = function($connection, $data)
{
    echo "Message Received: $data
";
};

Worker::runAll();

This code defines a new Workerman application and binds it to the local IP address on port 8000, using the websocket protocol. $worker->onConnect and $worker->onMessage are callback functions. When a new connection is established, the onConnect function will be executed. When a message from the client is received, the onMessage function will be executed.

4. Run the Workerman application

and save the index.php file. Then, you can open Terminal or Command Prompt, switch to the PHP project directory, and run the following command to start the Workerman application:

php index.php start

With this command, the Workerman application will run in the background and bind to the specified IP address and port. When a client connects to the application, it prints the "New Connection" text. When a message is received from the client, it will print the text "Message Received:" and display the content of the message.

5. Use more functions in Workerman

Workerman provides many functions that can help you create various types of applications. There are also some functions that can be used to handle network requests, such as:

• Timer: allows you to perform scheduled tasks.
• AsyncTcpConnection: Allows you to create an asynchronous TCP connection.
• UdpConnection: Lets you create a UDP connection.
