[PHP] Calculation assistance.. :)

[Stephen Johnson]

OK.. Math is NOT my forte ...

I am converting a site from ASP to PHP ... And this calc is in the ASP Code
: 

    $nMonthlyInterest = $nRate / (12 * 100)

    //' Calculate monthly payment
    $nPayment = $nPrincipal * ( $nMonthlyInterest / (1 - (1 +
$nMonthlyInterest) ^ -$iMonths))

Which then gives me in PHP
0.0010416666666667 = 1.25 / (12 * 100);
-2.1701388888889 = 25000 * ( 0.0010416666666667 / (1 - (1 +
0.0010416666666667) ^ -12)) ::

^  is the problem ...

The solution SHOULD be  2,097.47 ... Not ­2.17

Would be willing to help correct this and make it valid in PHP?
