What are the potential pitfalls of not accurately tracking user payments in a PHP system?

Not accurately tracking user payments in a PHP system can lead to discrepancies in financial records, loss of revenue, and potential legal issues. To solve this issue, it is important to implement a robust payment tracking system that accurately records all transactions and updates user payment statuses in real-time.

// Example of accurately tracking user payments in a PHP system

// Function to update user payment status
function updatePaymentStatus($userId, $amount) {
    // Code to update payment status in database
}

// Example usage
$userId = 123;
$paymentAmount = 50.00;
updatePaymentStatus($userId, $paymentAmount);
