From: carsten_sttgt at gmx dot de Operating system: Windows_NT PHP version: 5.2.9 PHP Bug Type: HTTP related Bug description: POST data is not decoded, according to Content-Transfer-Encoding
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 bug report at http://bugs.php.net/?id=48219&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48219&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48219&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48219&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48219&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48219&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48219&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48219&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48219&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48219&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48219&r=support Expected behavior: http://bugs.php.net/fix.php?id=48219&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48219&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48219&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48219&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48219&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48219&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48219&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48219&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48219&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48219&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48219&r=mysqlcfg
