Strtoupper Å Ä Ö fix UTF-8
As you might know the Stroupper dont work with special chars like Å Ä Ö. Also its not working to do str_replace sice Å Ä Ö is not supported there. But there is a way to do this easy with mb_stroupper and use UTF-8, see my example:
$string = “åäö”;
$string=mb_strtoupper($string, “utf-8″);
echo $string;
Enjoy!
$string=mb_strtoupper($string, “utf-8″);
