Here's a handy PHP function I developed that converts numbers into their verbose, English-language equivalents:
function numberToWords($n){
if($n < 1) return 'zero';
if($n > 1000000000000) return $n;
// Just return the number if it's out of a reasonable range for this application.
$n = intval($n); // We only deal with integers in this function.
$o = '';
$tens = Array('twenty','thirty','fourty','fifty','sixty','seventy','eighty','ninety');
$ones = Array(
'one',
'two',
'three',
'four',
'five',
'six',
'seven',
'eight',
'nine',
'ten',
'eleven',
'twelve',
'thirteen',
'fourteen',
'fifteen',
'sixteen',
'seventeen',
'eighteen',
'nineteen'
);
$units = Array(
'trillion' => 1000000000000,
'billion' => 1000000000,
'million' => 1000000,
'thousand' => 1000,
'hundred' => 100,
);
foreach($units as $unit => $amt){
$x = floor($n / $amt);
$n = $n - ($x * $amt);
$o .= ($x > 0) ? numberToWords($x).' '.$unit.' ' : ' ';
}
if($n >=20){ // Process tens.
$x = floor($n / 10);
$n = $n - ($x * 10);
$o .= ($x > 0) ? $tens[$x-2].' ' : ' ';
}
if($n > 0){ // Process ones.
$o .= $ones[$n-1];
}
return trim($o);
}
The function is mostly for aesthetic and novelty purposes but if you can find a good use for it, please take advantage of it.
If you use it, please let me know; you certainly don't have to tell me but I'm interested in hearing from anyone who finds it useful!
