PHP session_destroy – Destroy All Data in a Session

Function Definition bool session_destroy(void) The session_destroy() function destroys all data associated with the current session. It does not reset the global variables linked to the session nor does it delete the session cookie. To use session variables again after calling this function, you must invoke session_start() anew.

Parameters

None

Return Value

Returns TRUE on success, or FALSE on failure.

Example

<?php
// Initialize session.
session_start();

// Reset all session variables
$_SESSION = array();

// If you want to delete the session cookie as well
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();
?>
