Maybe it's possible. I wouldn't do it with a regex anymore though.

function _my_validate($string){
$array =3D explode('-',$string);
if(!is_array($array)) return false;
$previous =3D 0;
foreach($array as $value){
if(
intval($value)!=3D $value
||
$value < $previous
||
$value > 999
) return false;
$previous =3D $value;
}
return true;
}
