#28471 [NEW]: empty variable in url causes all other values to be lost

From: nico at kamensek dot de Operating system: Linux Kernel 2.4.26-grsec #1 SMP PHP version: 4.3.6 PHP Bug Type: Scripting Engine problem Bug description: empty variable in url causes all other values to be lost Description: ------------ This problem does not seem to be php 4.3.6 specific as I was able to successfully replicated it with php 4.3.4. The problem is, that a call like http://url/script.php?action=test works fine. If I add &var1= to the url, everything else is lost. The script acts as if I have called just script.php. But this problem only occurs in case I add a variable(var1 here) with no value. A test for that can be found at http://kamensek.de/test/test.php Try - test.php?action=test - test.php?action=test&var1= - test.php?action=test&var1=y and finally test.php?action=&var1=y which is no problem. The code is at http://kamensek.de/test/test.txt which is just a little example. PHP-config to that is located at http://kamensek.de/phpinfo.php This is *not* a register_globals problem. register_globals is on.
