How can PHP be used to track and update a user's progress towards reaching the maximum level in a level system?

To track and update a user's progress towards reaching the maximum level in a level system using PHP, you can store the user's current level and progress in a database. Then, whenever the user completes an action that contributes to their progress, you can update the progress value in the database. Finally, you can calculate the user's current level based on their progress and the level thresholds. 

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "level_system";

$conn = new mysqli($servername, $username, $password, $dbname);

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

// Get user's current progress
$user_id = 1; // Assuming user ID is 1
$sql = "SELECT progress FROM users WHERE id = $user_id";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    $row = $result->fetch_assoc();
    $progress = $row["progress"];
    
    // Calculate current level based on progress
    $max_level = 10;
    $level = floor($progress / ($max_level / 100)) + 1;
    
    echo "Current level: " . $level;
} else {
    echo "User not found";
}

// Update progress when user completes an action
$new_progress = $progress + 10; // Assuming user gains 10 progress
$sql = "UPDATE users SET progress = $new_progress WHERE id = $user_id";
$conn->query($sql);

// Close connection
$conn->close();
