#36526 [Bgs]: compressed data corruption when passed to another script via _REQUEST

ID: 36526 User updated by: terry at kryogenic dot co dot uk Reported By: terry at kryogenic dot co dot uk Status: Bogus Bug Type: *Compression related Operating System: Debian PHP Version: 5.1.2 New Comment: Sorry if this seems like its not a bug but I have been through the relevant channels already. urlencode does not work either, I should have mentioned that here (sorry). There is a difference between the strings after a decode of any sort. It sure looked like a bug when I reported it. Sorry I wasted your time. Previous Comments: ------------------------------------------------------------------------ [2006-02-25 16:09:10] mike@php.net Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. Treat the base64 encoded string with urlencode() prior passing in a link. ------------------------------------------------------------------------ [2006-02-25 13:21:32] terry at kryogenic dot co dot uk $decStr = bzdecompress(base64_decode($_REQUEST['error'])); should be $decStr = bzdecompress(base64_decode($_REQUEST['object'])); in the example code. My bad :) ------------------------------------------------------------------------ [2006-02-25 13:17:55] terry at kryogenic dot co dot uk Description: ------------ serializing, compressing and bzcompress/gzcompress an object then sending to another script via _REQUEST seems to cause corruption. bzdecompress returns error code -4. This following code works in php4 & php5.0.x but not 5.1.2. gzcompress also returns a very similar error. Reproduce code: --------------- script a) $compStr = bzcompress(serialize($an_array)); $base64Str = base64_encode($compStr); /* send this to script b like so: * http://somehost/script_b.php?object=$base64Str */ script b) $decStr = bzdecompress(base64_decode($_REQUEST['error'])); $array = unserialize($decStr); Expected result: ---------------- bzdecompress should succeed and after unserialization I should end up with the original array from script a. Actual result: -------------- bzdecompress returns -4 (data error) and unserialize would of course fail in the code above. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=36526&edit=1
