session_destroy
SESSION_DESTROY(3) 1 SESSION_DESTROY(3)session_destroy - Destroys all data registered to a sessionSYNOPSIS
bool session_destroy (void )
DESCRIPTION session_destroy(3) destroys all of the data associated with the current session. It does not unset any of the global variables associated
with the session, or unset the session cookie. To use the session variables again, session_start(3) has to be called.
In order to kill the session altogether, like to log the user out, the session id must also be unset. If a cookie is used to propagate the
session id (default behavior), then the session cookie must be deleted. setcookie(3) may be used for that.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Destroying a session with $_SESSION
<?php
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();
// Unset all of the session variables.
$_SESSION = array();
// If it's desired to kill the session, also delete the session cookie.
// Note: This will destroy the session, and not just the session data!
if (ini_get("session.use_cookies")) {
$params = session_get_cookie_params();
setcookie(session_name(), '', time() - 42000,
$params["path"], $params["domain"],
$params["secure"], $params["httponly"]
);
}
// Finally, destroy the session.
session_destroy();
?>
NOTES
Note
Only use session_unset(3) for older deprecated code that does not use $_SESSION.
SEE ALSO unset(3), setcookie(3).
