how to destroy exact session

Question

If i've $_SESSION["something"] and $_SESSION["else"] by using session_destroy() it will destroy both.

but what if i want only to destroy exact session which is $_SESSION["something"] and keeps $_SESSION["else"] active.

Answer 1

You can unset($_SESSION['something']) .

Bear in mind that these aren't separate sessions, they're entries in the same session id. You only have one active session.

Answer 2

$ _SESSION就像一个普通数组.....所以使用unset清除您想要的任何东西...如上一个答案中所建议.....

Answer 3

unset( $_SESSION['variable'] );

The above will not work with register_globals turned on (will only work outside of a function).

$variable = $_SESSION['variable']; unset( $_SESSION['variable'], $variable );

The above will work with register_globals on & inside a function
