Integers should be preferred over floats for calculations in PHP, especially for financial applications, to avoid precision errors that can occur with floating-point numbers. Using integers ensures that calculations are precise and accurate when dealing with financial data that requires exact values. 

// Using integers for financial calculations
$amount1 = 1000;
$amount2 = 500;

$total = $amount1 + $amount2;

echo $total; // Output: 1500
