How to implement the basic usage of Workerman documents

Introduction:
Workerman is a high-performance PHP development framework that can help developers easily build high concurrency web application. This article will introduce the basic usage of Workerman, including installation and configuration, creating services and listening ports, handling client requests, etc. And give corresponding code examples.

1. Install and configure Workerman

  1. Enter the following command on the command line to install Workerman:

    composer require workerman/workerman
  2. Create one File server.php, and import WorkermanWorker:

    require_once __DIR__ . '/vendor/autoload.php';
    
    use WorkermanWorker;
  3. Configure the running parameters of Workerman:

    $worker = new Worker('tcp://0.0.0.0:1234');
    $worker->count = 4;
    $worker->name = 'MyWorker';

    Among them, tcp://0.0.0.0:1234 means listening to the local 1234 port, count means starting 4 worker processes, name means setting a name for the current worker.

2. Create a service and listen on the port

  1. Add the following code in server.php to create the service and listen on the port :

    $worker->onWorkerStart = function($worker) {
     echo "Worker {$worker->id} started
    ";
    };
    
    $worker->onConnect = function($connection) {
     echo "Connection established: {$connection->id}
    ";
    };
    
    $worker->onMessage = function($connection, $data) {
     echo "Received data: {$data}
    ";
     $connection->send("Hello, $data");
    };
    
    $worker->onClose = function($connection) {
     echo "Connection closed: {$connection->id}
    ";
    };
    
    Worker::runAll();
  2. Run server.php in the command line:

    php server.php start

    This will create a service that listens to the local 1234 port.

3. Process client requests

  1. In another terminal or browser, enter the following command to connect to the server:

    telnet localhost 1234
  2. After the connection is successful, enter any string in the terminal and press Enter to send the data to the server.
  3. On the server terminal, you can see the received data and send it back to the client.
  4. Press Ctrl ] key to exit telnet.

4. Summary
Through the above code examples, we can see the basic usage of Workerman, including installation and configuration, creating services and listening ports, processing client requests, etc. With Workerman's powerful network processing capabilities, we can easily build highly concurrent network applications. I hope this article will help everyone understand and use Workerman.
