Convert upper to lower case

[mikaint]

HI,
I'm trying to convert some words to upper and lower case, using strtoupper() and strtolower() functions, and also ucwords() for capitalization of the first letter of those words. I'm using both greek and english languages, which are stored in my db using utf-8 encoding. All the functions are working for words in english, but not for words in greek. Can anybody help me with this? thanx.

You need to use the [url=http://us2.php.net/manual/en/ref.mbstring.php]mb_ functions[/url], if you can't use them, then you will need to create a simple convert function, using strtr(). If you can't setup the mb_ extension, then use...

[code]setlocale ( LC_CTYPE, 'el_GR' );

$str = strtoupper ( $str );

$str = strtolower ( $str );

$str = ucwords ( $str );[/code]


Where [b]'el_GR'[/b] is, it could also be just [b]'GR'[/b] or [b]'gr_GR'[/b] or just [b]'el'[/b], I say that because I have seen many different systems use each of these, so you have to test which one will work on the server you are running this on.

i've tried all cases. The first one (el_GR) will display Α������������������ Μ������������������������ Ο�������������� and all the other will display caps, as it is in the database...
