strtolower problem with some languages

[carsten888]

I'm trying to make a language string lowercase. strtolower works fine for most languages, but for some language this just returns ? (bunch of questionmarks, which are filtered out of this post).

<?php

echo strtolower('Hello');

?>

output:

hello

The file is correctly saved in utf-8 and the html-header is also in utf-8.

<?php

echo 'Strange language string (which this forum can not display)';

?>

outputs correctly.

So the problem is that when trying to make a string lowercase, in some languages the output becomes a bunch of questionmarks.

Is there a workaround to make the strings lowercase only for languages which support this?

Probably you could check some documentations of that language before using that code.Most languages have their way of writing these codes.

Have you considered the multibyte function [php.net] instead?

Yeah! thank you loads! livesaver.


$str = mb_strtolower($str, 'UTF-8');
