将UTF-8转换为ISO-8859-2（抛光）

Question

I have some problems downloading data event from facebook. I have a site , add.php , - this site is UTF-8 , next I'm sending a data to mysql ( utf-8 ) and then I'm displaying information on website ( iso-8859-2 ). Problem is when I'm displaying this data there are no polish signs.

How can I convert this data to iso-8859-2 like on original event facebook page?

I was trying iconv but it doesn't work:

function utf2iso( $tekst ) {
  iconv( "UTF-8", "ISO-8859-2", $tekst );
  return $tekst;
  };

Iconv doesn't works, please help - give me some advice!

PS. Sorry for my english :-)

Answer 1

iconv() returns converted text or false, but doesn't modify reference

function utf2iso( $tekst ) {
    return iconv( "UTF-8", "ISO-8859-2", $tekst );
};
