Re: ctype second opinions

The whole of the logic that I am trying to convey here similar to: $string = 'This is a string'; $i = 0; while ($string[$i] != '') {

should you be using $string{$i} ?? - cant remember the story on that but at one point it used to issue a warning if you used [] on a string. regards alan

$token = ''; while (strlen($string[$i]) && ctype_alpha($string[$i]) { $token .= $string[$i]; ++$i; } $tokens[] = $token; ++$i; } Wit
