решил таким извратом:


$var = explode('<br />', nl2br($body));
$new = array();

foreach($var as $line)
$new[] = (substr($line, -1) == '=')? substr(trim($line), 0, -1) : trim($line);

$body = mb_convert_encoding(urldecode(str_replace('=', '%', implode('', $new))), 'utf-8', 'auto');


а есть способ попроще?

[Kaimi]

<?php
print urldecode(str_replace(Array("=\r\n",'=','_'),Array('','%',' '),$body));
?>

[Дикс]

а зачем удалять _ ?

и тогда наверное так будет правильнее:


print urldecode(str_replace(Array("=" . PHP_EOL,'=','_'),Array('','%',' '),$body));

[krypt3r]

preg_replace ('/=([A-F0-9]{2})/e', 'chr(0x\\1)', $body);

[Дикс]

классно!

осталось только узнать, что это вообще такое:
=D0=BC=D0=BE=D0=B6=D0=BD=D0=B
и почему пхп это не понимает

[Kaimi]

http://en.wikipedia.org/wiki/Quoted-printable

[krypt3r]

тогда все еще проще

quoted_printable_decode()

Если не ошибаюсь, среди функций imap_* есть похожая, не помню точно, как называется
