How to Implement User Login Authentication Between PHP and Unity3D Using Workerman

In web application and game development, user login authentication is a core component. PHP is a popular language for web development, while Unity3D is widely used in game development. When combining these two technologies, the question of how to implement user login authentication between PHP and Unity3D becomes a common requirement. This article will guide you through the process of using the Workerman framework to achieve user login authentication between PHP and Unity3D.

1. What is Workerman?

Workerman is a high-performance, asynchronous, event-driven framework based on PHP, designed for building high-concurrency network applications. It supports both TCP and UDP protocols, making it suitable for building real-time messaging, game servers, and more. With its excellent performance, Workerman can easily handle large numbers of concurrent connections. It is an ideal choice for applications that require high performance and low latency.

2. Requirements Analysis

The goal here is to implement a PHP-based server for user login authentication, with the Unity3D client communicating with the PHP server to complete the login verification process. The specific flow is as follows:

1. The Unity3D client sends the username and password to the PHP server.
2. The PHP server verifies the correctness of the username and password.
3. The PHP server returns the verification result to the Unity3D client, and the client processes the result accordingly.

3. Code Implementation

Unity3D Client Code:

using System.Collections;
using UnityEngine;
using UnityEngine.Networking;
<p>public class LoginManager : MonoBehaviour<br>
{<br>
public string loginUrl = "<a rel="noopener" target="_new" class="" href="http://your-php-server.com/login.php">http://your-php-server.com/login.php</a>";<br>
public string username;<br>
public string password;</p>
<pre>public void Login()
{
    StartCoroutine(DoLogin());
}

IEnumerator DoLogin()
{
    WWWForm form = new WWWForm();
    form.AddField("username", username);
    form.AddField("password", password);

    UnityWebRequest www = UnityWebRequest.Post(loginUrl, form);
    yield return www.SendWebRequest();

    if (www.isNetworkError || www.isHttpError)
    {
        Debug.Log(www.error);
    }
    else
    {
        Debug.Log(www.downloadHandler.text);
    }
}

}

PHP Server Code:

require_once __DIR__ . '/workerman/Autoloader.php';
use Workerman\Worker;
<p>$worker = new Worker('tcp://0.0.0.0:8000');</p>
<p>$worker->onMessage = function($connection, $data) {<br>
$requestData = json_decode($data, true);<br>
$username = $requestData['username'];<br>
$password = $requestData['password'];</p>
<pre>// Validate the username and password
if ($username == 'admin' && $password == '123456') {
    $connection->send(json_encode(['result' => true]));
} else {
    $connection->send(json_encode(['result' => false]));
}

};

Worker::runAll();

4. Usage Instructions

1. First, download and extract the Workerman framework to a directory on your PHP server, for example: /path/to/workerman.
2. Create a login interface in Unity3D and bind the above Unity3D client code to the OnClick event of the login button.
3. Save the above PHP server code as login.php on your PHP server, placing it in a directory that can be accessed by a web server.
4. Start the Workerman server: php /path/to/workerman/start.php start -d.
5. Run the Unity3D client, enter the correct username and password, and click the login button. The Unity3D client will send the login request to the PHP server, which will return the validation result for the username and password.

5. Conclusion

This article demonstrated how to implement user login authentication between PHP and Unity3D using the Workerman framework. Through the provided code examples, you can easily establish an efficient login authentication system between the Unity3D client and the PHP server. Workerman's high-performance features make communication between PHP and Unity3D smooth, especially in high-concurrency scenarios.
