ID: 44570 Updated by: [EMAIL PROTECTED] Reported By: tokul at users dot sourceforge dot net -Status: Open +Status: Bogus Bug Type: mbstring related Operating System: Linux Debian Etch PHP Version: 5.2CVS-2008-03-30 (snap) New Comment:
Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php That's exactly why mb_encode_mimeheader() converts the given string and encode it to MIME encoding at the same time. You may have been confused by the fact mb_encode_mimeheader() does not take an argument that specifies the encoding of the supplied string contrary to other mbstring functions. You should make sure that the internal encoding is set to the correct value prior to using it. <?php $string = "\xe7\xa7\x8b\xe3\x81\xae\xe7\x94\xb0\xe3\x81\xae\x20" ."\xe3\x81\x8b\xe3\x82\x8a\xe3\x81\xbb\xe3\x81\xae\xe5\xba\xb5" ."\xe3\x81\xae\x20\xe8\x8b\xab\xe3\x82\x92\xe3\x81\x82" ."\xe3\x82\x89\xe3\x81\xbf\x20\x20\xe3\x82\x8f\xe3\x81\x8c" ."\xe8\xa1\xa3\xe6\x89\x8b\xe3\x81\xaf\x20\xe9\x9c\xb2" ."\xe3\x81\xab\xe3\x81\xac\xe3\x82\x8c\xe3\x81\xa4\xe3\x81\xa4"; mb_internal_encoding("utf-8"); //$string = mb_convert_encoding($string,'iso-2022-jp','utf-8'); echo mb_encode_mimeheader($string,'iso-2022-jp','b'); ?> Previous Comments: ------------------------------------------------------------------------ [2008-03-30 12:45:55] tokul at users dot sourceforge dot net If mbstring.internal_encoding is set, code does not need mb_convert_encoding() call. ------------------------------------------------------------------------ [2008-03-30 12:28:18] tokul at users dot sourceforge dot net Description: ------------ mb_encode_mimeheader incorrectly folds iso-2022 texts. rfc 2047 chapter 3 second paragraph says that folded string must be reverted to ASCII. Code just splits ISO-2022 string without adding appropriate escapes. Code works as expected only when mbstring.internal_encoding is set to correct value. This dependency of mb_encode_mimeheader() is not documented and catches all users that are not used to mb_encode_mimeheader() quirks.
