How can one troubleshoot and resolve issues when implementing PHP code for loan calculations?

Issue: One common issue when implementing PHP code for loan calculations is incorrect mathematical calculations leading to inaccurate results. To resolve this, ensure that the formula used for calculating loan amounts, interest rates, and repayment schedules is accurate and properly implemented. 

// Example PHP code snippet for accurate loan calculations

$loanAmount = 10000; // Loan amount in dollars
$interestRate = 5; // Annual interest rate in percentage
$loanTerm = 3; // Loan term in years

// Calculate monthly interest rate
$monthlyInterestRate = ($interestRate / 100) / 12;

// Calculate monthly payment using the formula
$monthlyPayment = ($loanAmount * $monthlyInterestRate) / (1 - pow(1 + $monthlyInterestRate, -$loanTerm * 12));

// Display the monthly payment
echo "Monthly Payment: $" . number_format($monthlyPayment, 2);
