This function takes a numeric currency value - say 34.87, and converts it to a string as in Thirty Four Dollars and Eighty Seven Cents. Handles amounts up to 999 million. Handles singular and plural "dollars" and "cents". Decently documented and easy to follow.
PHP Example :
<?php
//*************************************************************
// this function converts an amount into alpha words
// with the words dollars and cents. Pass it a float.
// Example: $3.77 = Three Dollars and Seventy Seven Cents
// works up to 999,999,999.99 dollars - Great for checks
//*************************************************************
function makewords($numval)

// handle the millions
$milval = (integer)($numval / 1000000);
if($milval > 0)
{
$moneystr = getwords($milval) . " Million";
}
// handle all the rest of the dollars
$workval = $workval - ($thouval * 1000); // get rid of thousands

$workval = (integer)($numval);
if ($workval == 1)
{

}
else
{

}
// do the pennies - use printf so that we get the
// same rounding as printf
