#18996 [NEW]: Can't unset() the session variables

From: frank@orite.com Operating system: Redhat Linux 7.3 PHP version: 4.2.2 PHP Bug Type: Session related Bug description: Can't unset() the session variables Apache/1.3.23 (Unix) (Red-Hat/Linux) register_globals = Off [Session] session.save_handler = files session.save_path = /tmp session.use_cookies = 1 session.name = PHPSESSID session.auto_start = 0 session.cookie_lifetime = 0 session.cookie_path = / session.cookie_domain = session.serialize_handler = php session.gc_probability = 1 session.gc_maxlifetime = 1440 session.referer_check = session.entropy_length = 0 session.entropy_file = ;session.entropy_length = 16 ;session.entropy_file = /dev/urandom session.cache_limiter = nocache session.cache_expire = 180 session.use_trans_sid = 1 url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=fakeentry" I was trying to test the session via two pages, test.php and test2.php. Following are the scripts and results come up: test.php <?php session_start(); $_SESSION["user"]="foo"; echo "set:".$_SESSION["user"]; unset($_SESSION); echo "<br>unset:".@$_SESSION["user"]; ?> result on page: set:foo unset: test2.php <?php session_start(); echo "set:".$_SESSION["user"]; echo "<br>unset:".@$_SESSION["user"]; ?> result on page: set:foo unset:foo I've also tried to put up a session_destory() in test.php, that helps to unset the variable, but simply the session no longer exists. Does anyone has the same problem, or any answers to this issue? -- Edit bug report at http://bugs.php.net/?id=18996&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=18996&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=18996&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=18996&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=18996&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=18996&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=18996&r=support Expected behavior: http://bugs.php.net/fix.php?id=18996&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=18996&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=18996&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=18996&r=globals
