ID: 54703 User updated by: php at tracking-celebs dot info Reported by: php at tracking-celebs dot info Summary: When containing a null character, $_GET variable not set (properly) -Status: Feedback +Status: Open Type: Bug Package: *General Issues PHP Version: 5.2.17 Block user comment: N Private report: N New Comment: On that linux machine there is suhosin indeed, so it could be causing the problem. I just tried on another computer with a new vanilla php-5.2.17 and then got the same results as did on windows. Would seem indeed to be caused by suhosin; however i just added suhosin on there and it still worked then as before, so there must be something else on that other computer... Anyways, can't reproduce it with a vanilla php, so that's that. I got things mixed up, seems there's no bug here after all; Apologies. Previous Comments: ------------------------------------------------------------------------ [2011-05-10 19:39:23] ras...@php.net On Linux this is not true unless you have something specifically filtering these on you. Without ext/filter, suhosin or your own filter code, nulls go through fine. See: http://progphp.com/null.php?fb=foo%00bar And the source for the script: http://progphp.com/null.phps And it shouldn't be any different on Windows. ------------------------------------------------------------------------ [2011-05-10 19:21:28] php at tracking-celebs dot info Description: ------------ When a null character is present in the value of a variable in the request string (encoded as %00), said variable will either not be set in $_GET at all (linux) or be set improperly (null character is escaped; win32) Test script: --------------- <?php print_r($_GET); if (isset($_GET['fb'])) { echo strlen($_GET['fb']); } else { echo '<a href="?fb=foo%00bar">click me</a>'; } Expected result: ---------------- After clicking the link: Array ( [fb] => foo�bar ) 7 Actual result: -------------- After clicking the link: - On a linux setup: Array ( ) <a href="?fb=foo%00bar">click me</a> - On a win32 setup: Array ( [fb] => foo\0bar ) 8 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54703&edit=1
