In PHP:
function RomanDigit($dig, $one, $five, $ten) {
switch($dig) {
case 0: return "";
case 1: return "$one";
case 2: return "$one$one";
case 3: return "$one$one$one";
case 4: return "$one$five";
case 5: return "$five";
case 6: return "$five$one";
case 7: return "$five$one$one";
case 8: return "$five$one$one$one";
case 9: return "$one$ten";
}
}
function IntToRoman($num) {
if (($num < 1) || ($num > 3999))
return("No corresponding Roman number!");
$m = $num / 1000;
$c = ($num % 1000) / 100;
$x = ($num % 100) / 10;
$i = $num % 10;
return(
RomanDigit($m, 'M', '', '')
.RomanDigit($c, 'C', 'D', 'M')
.RomanDigit($x, 'X', 'L', 'C')
.RomanDigit($i, 'I', 'V', 'X')
);
}
