问题 session_start(); $_SESSION['user'] = "789456"; $_SESSION['name'] = "dummy"; $_SESSION['id'] = "123"; print_r($_SESSION); session_destroy(); echo "Session End"; print_r($_SESSION); My output is: Array ( [user] => 789456 [name] => dummy [id] => 123) Session End :Array ( [user] => 789456 [name] => dummy [id] => 123) Shouldn't the output just be: Array ( [user] => 789456 [name] => dummy [id] => 123) If I use session_unset() before session_destroy() then I get the result I expect.

问题 postgresql-9.0.15 on CentOS 6.5. I have a plperlu function that outputs an INFO message.
