What are the potential risks of inexperienced individuals attempting to develop a browser game using PHP?

Inexperienced individuals attempting to develop a browser game using PHP may encounter security vulnerabilities, inefficient code structure, and performance issues. To mitigate these risks, it is essential for developers to thoroughly understand PHP best practices, security measures, and game development principles. 

<?php

// Example of implementing a secure login system in PHP

// Start session
session_start();

// Check if user is already logged in
if(isset($_SESSION['user_id'])) {
    // User is already logged in, redirect to game page
    header("Location: game.php");
    exit();
}

// Validate user input
if($_SERVER["REQUEST_METHOD"] == "POST") {
    // Check if username and password are correct
    $username = $_POST['username'];
    $password = $_POST['password'];

    // Add your validation logic here

    // If credentials are correct, set session variables and redirect to game page
    $_SESSION['user_id'] = $user_id;
    header("Location: game.php");
    exit();
}
