Try this:
<?php
error_reporting(E_ALL);

mb_internal_encoding('UTF-8');

checkString('=?iso-8859-1?B?RGlhbmEgQ3Jpc3TzYmFs?=');
checkString('=?KOI8-R?B?6dLJzsEg78zaz8XXwQ==?=');

function checkString($s) {
	echo 'input: '.$s.'<br>';
	$s = mb_decode_mimeheader($s);
	echo 'output: '.charset_decode_utf_8($s).'<br><br>';
}

// this from: http://php.net/manual/en/function.utf8-decode.php
function charset_decode_utf_8 ($string) {
      /* Only do the slow convert if there are 8-bit characters */
    /* avoid using 0xA0 (\240) in ereg ranges. RH73 does not like that */
    if (! ereg("[\200-\237]", $string) and ! ereg("[\241-\377]", $string))
        return $string;

    // decode three byte unicode characters
    $string = preg_replace("/([\340-\357])([\200-\277])([\200-\277])/e", "'&#'.((ord('\\1')-224)*4096 + (ord('\\2')-128)*64 + (ord('\\3')-128)).';'", $string);

    // decode two byte unicode characters
    $string = preg_replace("/([\300-\337])([\200-\277])/e", "'&#'.((ord('\\1')-192)*64+(ord('\\2')-128)).';'", $string);

    return $string;
}

?>

That decode function was in the comments in the manual of utf8_decode, apparently taken from the sources of SquirrelMail. Nice!

Important also is setting that internal encoding, could also be done in php.ini I guess.

EDIT: some more info, I tried 'everything' related to doctype, meta tags, php header setting of charset (needed according to a lot of other solutions), physical file type (needed for literals in the page) etc but took it all out and it still works, no meta, no charset header, showing cyrillic text. Just the internal encoding seems important, as well as the alternative way to handle htmlentities.

I've tried a couple of things, maybe with your local server encoding in php.ini it works:

iconv_mime_decode('=?KOI8-R?B?6dLJzsEg78zaz8XXwQ==?=', 0, 'koi8-r');

Open in new window


$new = mb_convert_encoding($str, 'windows-1251', 'KOI8-R');

Well, in my scripts I can't get the cyrillic to print out well. Whereas this guy is capable of transcoding it into cyrillic:

Maybe he can help you with your problem.

Do you mean the output on my link? Or the code works for you? If the latter, then we're done? ;-)
