What are some best practices for representing different interest rates and fees for loans in PHP?

When representing different interest rates and fees for loans in PHP, it's best practice to use variables to store these values separately for easy manipulation and calculation. This allows for flexibility in adjusting rates and fees without having to modify multiple parts of the code. Additionally, using clear and descriptive variable names can improve code readability and maintainability. 

// Define interest rates and fees as variables
$interestRate = 0.05; // 5%
$processingFee = 50.00;

// Calculate total amount with interest and fees
$loanAmount = 1000.00;
$totalAmount = $loanAmount + ($loanAmount * $interestRate) + $processingFee;

echo "Total amount to repay: $" . number_format($totalAmount, 2);
