How to Completely Wipe Out a PHP Session Even with Open Browsers?

Best Way to Wipe Out Sessions Even with Open Browsers

To eliminate a session entirely, even if the browser remains open, it's imperative to address multiple aspects. While session_start(), unset($_SESSION), session_unset(), and session_destroy() are crucial steps, further measures are necessary.

According to the official PHP documentation, it's vital to remove the session identifier to abolish the session permanently. This involves deleting the session cookie if it's being used to disseminate the session ID. setcookie() proves effective in this regard.

Below is an inclusive example of how to execute this procedure:

<code class="php"><?php

// Initiate the session.
// Include `session_name("something")` if used previously.
session_start();

// Remove all session variables.
$_SESSION = array();

// Erase the session cookie to terminate the session.
if (ini_get("session.use_cookies")) {
    $params = session_get_cookie_params();
    setcookie(session_name(), '', time() - 42000,
        $params["path"], $params["domain"],
        $params["secure"], $params["httponly"]
    );
}

// Conclude by wiping out the session.
session_destroy();

?></code>
