Convert from Roman to Arabic bug

Hi,
example code

$converter = new ConvertRoman("MMDCCXXVII");
echo $converter->result().'<br>';

returns

MMDCCXXVII2727

Aha, I have to delete the command "print..." in the class.
Good joke ;)

$number = 8000;
$converter = new ConvertRoman($number);
$rom = $converter->result();
echo $converter->result().'===&gt;';
$converter = new ConvertRoman($rom);
echo $converter->result().'<br>';

returns right values by your class rules

_VMMM===>8000 , right roman value by convention is VIIIM or VIII.M


$number = 4000;
$converter = new ConvertRoman($number);
$rom = $converter->result();
echo $converter->result().'===&gt;';
$converter = new ConvertRoman($rom);
echo $converter->result().'<br>';

returns bad arabic value

M_V===>6000 , right roman value by convention is IVM or IV.M
