#48219 [Opn]: POST data is not decoded, according to Content-Transfer-Encoding

ID: 48219 Updated by: jani@php.net Reported By: carsten_sttgt at gmx dot de Status: Open Bug Type: Feature/Change Request Operating System: * PHP Version: 5.*, 6CVS (2009-05-09) New Comment: btw. Fastest way to get this implemented is by providing a patch. :) Previous Comments: ------------------------------------------------------------------------ [2009-05-10 17:01:57] jani@php.net Unfortunately this is a feature request so reclassifying as such. And this is (I think :) related also to bug #37860 and maybe some others I couldn't find. :) ------------------------------------------------------------------------ [2009-05-10 10:49:28] carsten_sttgt at gmx dot de Description: ------------ Hallo, In a HTTP POST request and Content-Type "multipart/form-data", each part can have a Content-Transfer-Encoding, which is defined in RFC2045. (See also HTML 4.01-sec17.13.4.2) PHP only works with 7bit, 8bit and binary, because with these values, the data is not transformed. With base64 or quoted-printabled, the data is transformed (encoded), and PHP should decode it (see also rfc2616-sec3.7.2 / rfc1867-sec3.3). Just test the above example from RFC2388-sec4.5. That's also a problem, if you upload a file with such a transfer encoding. After move_uploaded_files, the content of such file is not really what you aspect. And in a script, which receives such data, I don't see (can't know), if there was a Content-Transfer-Encoding for something in $_POST / $_FILES. Maybe not usual, but a Client can use such a Content-Transfer-Encoding at any time in a POST request. Regards, Carsten Reproduce code: --------------- Create a simple "test.php" in your DocumentRoot: ================== <?php var_dump($_POST); ?> ================== Telnet to localhost:80 and send this request: ====================================================== POST http://localhost/test.php HTTP/1.0 Content-Length: 181 Content-Type: multipart/form-data; boundary=AaB03x --AaB03x Content-Disposition: form-data; name="field1" Content-Type: text/plain;charset=windows-1250 Content-Transfer-Encoding: quoted-printable Joe owes =80100. --AaB03x-- ====================================================== Expected result: ---------------- array(1) { ["field1"]=> string(14) "Joe owes €100." } Actual result: -------------- array(1) { ["field1"]=> string(16) "Joe owes =80100." } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48219&edit=1
