// Assume this file updates the balance in the database and returns the updated balance
// You need to implement the logic to update the balance in your database here

// Sample logic: Increment the balance by a random amount for demonstration purposes
$user['balance'] += rand(1, 10);

// Convert the updated balance to the currency format
$updatedBalance = currency($user['balance'], $settings['currency_rate']);

// Output the updated balance
echo $updatedBalance;
