Strangely, I was working on an alphabetic base convertor recently.

What have you tried? - show your code

<?
$char='T';
$lastchar="AR";
$last=++$lastchar;
for($l=$char;$l!=$last;$l++){
    echo $l;
}
?>

I have done.
Thanks

Yep, I think that's as good as it can get :)

I'm assuming though that you allow A and AA and AAA as distinct entities. If you were using base26 (purely alphabetical and not alphanumeric), they would all be equivalent (i.e. = 0).
