#22642 [Fbk->Csd]: After saving a session var in a var, nulling the session var clears the 2nd var

ID: 22642 User updated by: dave at orangechicken dot com Reported By: dave at orangechicken dot com -Status: Feedback +Status: Closed Bug Type: Session related Operating System: Linux / Apache 1.3.27 PHP Version: 4.3.1 New Comment: I'm uber-tarded. I found the solution an hour later or so (and it's the same one suggested above). I used an .htaccess file to turn register_globals off. I had been working in my dev environment so long (with register_globals off in php.ini) that I didn't even think about that when I moved to the live environment (which defaults to on). My bad. Case closed. Previous Comments: ------------------------------------------------------------------------ [2003-03-11 21:07:22] sniper@php.net Please provide a short but complete example script. And is register_globals=off ? And what about session.bug_compat_42 and session.bug_compat_warn? Put 'error_reporting(E_ALL);' as first line in your script, you propably get some errors.. ------------------------------------------------------------------------ [2003-03-11 15:54:35] dave at orangechicken dot com OK, the summary was too short to concisely enter what I mean. Here's the real version: After assigning a stored $_SESSION var to another variable, assigning null to the $_SESSION var clears the other variable too. This worked before 4.3.1 (possibly occurred in 4.3.0 - we skipped from 4.2.7 to 4.3.1). Here's a snippet where the problem occurs. $_SESSION[ 'login_redirect' ] contains the value 'checkout.php'. ================================ $redirect = $_SESSION[ 'login_redirect' ]; echo $redirect; // outputs checkout.php $_SESSION[ 'login_redirect' ] = null; echo $redirect; // outputs <nothing> ================================ Here's the configure string './configure' '--with-apxs=/usr/local/apache/bin/apxs' '--with-xml' '--enable-bcmath' '--enable-calendar' '--with-curl' '--enable-ftp' '--with-gd' '--with-jpeg-dir=/usr/local' '--with-png-dir=/usr' '--with-xpm-dir=/usr/X11R6' '--with-imap' '--with-imap-ssl' '--with-kerberos' '--with-mcrypt' '--enable-magic-quotes' '--with-mysql' '--with-pear' '--enable-xslt' '--with-xslt-sablot' '--enable-sockets' '--enable-track-vars' '--with-ttf' '--with-freetype-dir=/usr' '--enable-gd-native-ttf' '--enable-versioning' '--with-zlib' ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=22642&edit=1
