<?php
function RentalPayment($Principle, $IntRate, $PayPerYear, $NumYears)

            $numer; $denom; $b; $e; 
             
            $numer = $IntRate * $Principle / $PayPerYear; 

            $e = -($PayPerYear * $NumYears); 

            $b = ($IntRate / $PayPerYear) + 1; 

            $denom = 1 - pow($b, $e); 

            return $numer / $denom;
