ID: 14321 User updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Bogus Bug Type: Variables related Operating System: i686-gnu-linux Old PHP Version: 4.1.0 PHP Version: 4.2.0dev Old Assigned To: sterling Assigned To: New Comment:
[EMAIL PROTECTED] said (via email) "If PHP is not following RFC1867, someone will fix it.". Actually it's hard to say, if binary data _has_ to be supported in post variables (multipart/form-data), as far as rfc1867 is concearned. I already discussed that with Daniel Stenberg (libcurl) [[EMAIL PROTECTED]] and he said, that PHP should support that from his point of view. Anyway it would be very helpful, if it was possible to send binary data w/o writing the data to a file and reading it again and of course w/o encoding the data prior to sending it ( for performance reasons). As far as I understand Sterling, PHP was expected to behave that way (not only with file-posts). I just finished an example which demonstrates, that the data is beeing truncated by PHP, somewhere between $HTTP_RAW_POST_DATA and transferring it to $_POST. You can download the sample from: http://www.kranzhoff.de/php/bug14321.bz2 It contains a small C prog which sends the data and a corresponding PHP-script which receives the data. Hanno Previous Comments: ------------------------------------------------------------------------ [2001-12-13 12:37:53] [EMAIL PROTECTED] Ok, I tried $HTTP_RAW_POST_DATA. The result of "echo rawurlencode($HTTP_RAW_POST_DATA);" is : ##### --curl0m0Kw3o0o1CufhI8a%2BHAFaguSrD%0D%0A Content-Disposition%3A%20form-data%3B%20name%3D%22BinaryData%22%0D%0A%0D%0A A%00B%0D%0A --curl0m0Kw3o0o1CufhI8a%2BHAFaguSrD--%0D%0A ##### So it seems that PHP receives the data (A%00B) correctly. But why doesn't $_POST reveal the same data ? Is there something wrong with reassembling the data of the post in PHP (maybe in rfc1867.c) ? Or is there another way of getting the data w/o the rfc1867 stuff (e.g. boundaries) besides "$_POST" ? Hanno ------------------------------------------------------------------------ [2001-12-13 06:45:23] [EMAIL PROTECTED] Try $HTTP_RAW_POST_DATA. Encode data with base64 or like when you print, if there is null char in data. Then you should be able to deal with. ------------------------------------------------------------------------ [2001-12-13 05:31:15] [EMAIL PROTECTED] Sorry, this is not a bogus. I wish it was. Obviously Sterling got me completely wrong. It's not a problem of printing binary data. As I do not use curl with PHP this bug is NOT Curl related it's more in the receiving end. What I'm doing is posting binary data using libcurl with c++. In this example it's a buffer containing A,chr(0) and B. Network traces show the following: ######## POST /test.php HTTP/1.1. Pragma: no-cache. Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */*. Content-Length: 130. Content-Type: multipart/form-data; boundary=curl/49TVuznugm1TDG2p68EyKJrXOq. . --curl/49TVuznugm1TDG2p68EyKJrXOq. Content-Disposition: form-data; name="BinaryData". . A.B. --curl/49TVuznugm1TDG2p68EyKJrXOq--. ######## I hope everybody agrees that the post is ok and that it's containing 3 byte of data (A,chr(0) and B). So I do not present the C++ code here, as it is obviously not relevant. On the PHP side I check the received data with: ######## echo "POST: "; print_r($_POST); //and just to make sure print_r is binary safe... $foo="X".chr(0)."Z"; print_r($foo); ######## the result is: ######## POST: Array ( [BinaryData] => A ) X.Z ######## So everything following "A" including chr(0) has been truncated. Again this problem has been mentioned on 2001-06-16 by [EMAIL PROTECTED] in bug report #11516. Additionally if I change the name of the post variable to ### name="BinaryData" filename="foo" ### to trick PHP into believing it's a ordinary file post the received file contains all the 3 bytes. This should prove that the post itself is ok. Tell me if you want me to present the c source code or do some different kind of testing. Tests were done with PHP 4.1.0 and the latest CVS version. Hanno ------------------------------------------------------------------------ [2001-12-03 09:36:46] [EMAIL PROTECTED] a) not a cURL related bug report b) bogus, when you print binary data, expect it to be truncated at the NULL, this is the same in every language. ------------------------------------------------------------------------ [2001-12-03 06:23:56] [EMAIL PROTECTED] Assigning to sterling, the cURL master.
