Here's a simple PHP code for an amortizing loan calculator

<?php
$principal = 100000; // loan amount
$interestRate = 5; // interest rate
$term = 360; // loan term in months
$monthlyPayment = ($principal * ($interestRate/1200)) / (1 - pow(1 + ($interestRate/1200), -$term));
$balance = $principal;

echo "<table>";
echo "<tr><th>Month</th><th>Payment</th><th>Principal</th><th>Interest</th><th>Balance</th></tr>";
for ($i = 1; $i <= $term; $i++) {
    $interest = $balance * ($interestRate/1200);
    $principal = $monthlyPayment - $interest;
    $balance = $balance - $principal;
    echo "<tr><td>".$i."</td><td>$".number_format($monthlyPayment, 2)."</td><td>$".number_format($principal, 2)."</td><td>$".number_format($interest, 2)."</td><td>$".number_format($balance, 2)."</td></tr>";
}
echo "</table>";
?>

This code calculates the monthly payment for a loan using the given principal, interest rate, and term in months. It then iterates over the loan term, calculating the principal, interest, and balance for each month, and displays the results in a table. The number_format() function is used to format the output to two decimal places. You can modify the values of $principal, $interestRate, and $term to fit your specific loan details.
