UTF-8 problems PHP/MySQL

I've always used ISO-8859-1 encoding, but I'm now going over to UTF-8.

Unfortunately I can't get it to work.

My MySQL DB is UTF-8, my PHP document is encoded in UTF-8, I set a UTF-8 charset, but it still doesn't work.

(it is special characters like æ/ø/å that doesn't work)

Hope you guys can help!

Answer

Make sure the connection to your database is also using this character set:

$conn = mysql_connect($server, $username, $password);
mysql_set_charset("UTF8", $conn);

According to the documentation of mysql_set_charset at php.net:

Note:
This is the preferred way to change the charset. Using mysql_query() to execute 
SET NAMES .. is not recommended.

Check the character set of your current connection with:

echo mysql_client_encoding($conn);

If you have done these things and add weird characters to your table, you will see it is displayed correct.
