What are the advantages of storing monetary amounts in cents as integers rather than floats in PHP?

Storing monetary amounts in cents as integers rather than floats in PHP helps to avoid precision errors that can occur when performing arithmetic operations on floating-point numbers. This approach ensures accurate calculations when dealing with currency values.

// Storing monetary amounts in cents as integers
$amountInCents = 1000; // $10.00
$discountInCents = 250; // $2.50

// Performing arithmetic operations with integer values
$totalAmountInCents = $amountInCents - $discountInCents;
$totalAmount = $totalAmountInCents / 100; // Convert back to dollars
echo "Total amount: $" . number_format($totalAmount, 2);
