php tutorial to determine page input character encoding method

function convtoutf8($str)
{
if( mb_detect_encoding($str,"utf-8, iso-8859-1, gbk")!="utf-8" )
{

return iconv("gbk","utf-8",$str);

}
else
{
return $str;
}

}
?>

However, some friends said that the mb_detect_encoding function does not support gbk and only supports utf-8, utf-7, ascii, euc-jp, sjis, eucjp-win, sjis-win, jis, iso-2022-jp and iso-8859 -*
You can test it, I haven’t tested it.

/* detect character encoding with current detect_order */
echo mb_detect_encoding($str);

/* "auto" is expanded according to mbstring.language */
echo mb_detect_encoding($str, "auto");

/* specify encoding_list character encoding by comma separated list */
echo mb_detect_encoding($str, "jis, eucjp-win, sjis-win");

/* use array to specify encoding_list */
$ary[] = "ascii";
$ary[] = "jis";
$ary[] = "euc-jp";
echo
