根据手册,还有更多工作要做:
为了完全终止会话,例如注销用户,还必须取消设置会话ID。如果 Cookie 用于传播会话 ID(默认行为),则必须删除会话 Cookie。setcookie() 可以用于此目的。
手动链接有一个完整的工作示例,说明如何做到这一点。从那里偷来的:
<?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();
?>
