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')
    );
}
