Phaser 3 javascript browser based game architecture with backend as PHP and database as MySql for leaderboard

Creating a Phaser 3 JavaScript browser-based game with a backend in PHP and a MySQL database for a leaderboard involves several components. Here’s a high-level overview of the architecture and steps you can follow:

Frontend (Phaser 3)

  1. Setup Phaser 3:
    • Download Phaser 3 or include it through a CDN in your HTML file.
    • Create a basic Phaser game structure with a scene for gameplay.
  2. Implement Leaderboard UI:
    • Design and implement the leaderboard UI within your Phaser game.
    • Display player scores and names.
  3. Handle Score Submission:
    • When a player finishes a level or achieves a high score, send the score to the backend for storage.
  4. Communicate with Backend:
    • Use AJAX or fetch API to send data (e.g., player name and score) to the backend.

Backend (PHP)

  1. Create Database:
    • Set up a MySQL database to store leaderboard information.
    • Create a table to store player names and scores.
  2. Implement PHP Scripts:
    • Create PHP scripts to handle data from the frontend.
    • Establish a connection to the MySQL database.
  3. Handle Score Submission:
    • Receive data from the frontend, extract player name and score.
    • Insert the data into the MySQL database.
  4. Retrieve Leaderboard Data:
    • Create a script to retrieve the top scores from the database.
    • Sort the scores and send them back to the frontend.

Database (MySQL)

  1. Design Database Table:
    • Design a table to store leaderboard data. Include columns for player names and scores.
  2. Handle Score Submission:
    • Create a SQL query to insert player names and scores into the table.
  3. Retrieve Leaderboard Data:
    • Create a SQL query to retrieve the top scores from the table.
    • Order the results by score in descending order.

Integration

  1. Frontend-Backend Integration:
    • Ensure that your frontend can communicate with the backend using AJAX or the fetch API.
    • Send data to the PHP scripts and handle responses.
  2. Test:
    • Test the complete flow. Ensure that scores are submitted and retrieved correctly.

Security Considerations:

  1. Validation:
    • Validate user input on both the frontend and backend to prevent SQL injection and other security vulnerabilities.
  2. Authentication:
    • Consider implementing user authentication if needed to ensure that only authorized users can submit scores.
  3. HTTPS:
    • Use HTTPS to secure data transmission between the frontend and backend.

Example Code (Simplified):

Frontend (Phaser 3):

// Submit score to backend
function submitScore(playerName, score) {
  fetch('backend/savescore.php', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ playerName, score }),
  });
}

// Retrieve leaderboard from backend
function getLeaderboard() {
  fetch('backend/getleaderboard.php')
    .then(response => response.json())
    .then(data => {
      // Update leaderboard UI with data
    });
}

BackEnd PHP

<?php
// savescore.php

// Retrieve data from the frontend
$data = json_decode(file_get_contents('php://input'), true);
$playerName = $data['playerName'];
$score = $data['score'];

// Insert data into the database
// Note: Implement proper validation and security measures
$conn = new mysqli("localhost", "username", "password", "dbname");

if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}

$sql = "INSERT INTO leaderboard (playerName, score) VALUES ('$playerName', $score)";
$conn->query($sql);
$conn->close();
?>
<?php
// getleaderboard.php

// Retrieve leaderboard data from the database
// Note: Implement proper validation and security measures
$conn = new mysqli("localhost", "username", "password", "dbname");

if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}

$sql = "SELECT playerName, score FROM leaderboard ORDER BY score DESC LIMIT 10";
$result = $conn->query($sql);

$leaderboard = array();
while ($row = $result->fetch_assoc()) {
  $leaderboard[] = $row;
}

header('Content-Type: application/json');
echo json_encode($leaderboard);

$conn->close();
?>

Remember, this is a simplified example, and you should enhance it based on your specific needs and security considerations. Additionally, always use prepared statements and parameterized queries to prevent SQL injection attacks.
