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. If you pass arbitrary data as GET parameter, you have to urlencode() them anyway.

I'm not sure why a serialized object is using a null byte for private or protected members in the first place, as null bytes are used for termination. Test script: --------------- on the server: <?php print_r($_REQUEST); ?> Expected result: ---------------- If we send a request: GET /bla.php? rest_data=O:14:"LoadsCacheFile":11{s:12:"\x00*\x00_FileName";s:5:"Cache";} HTTP/1.0 Host: 192.168.98.134 reply: 'array (\n' array ( 'rest_data' => 'O:14:"LoadsCacheFile":11:{s:12:"', ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61035&edit=1
