PHP Session（$ _SESSION []）正在工作甚至破坏会话

Question

Here is a code I destroy the session but it still working.

<?php
 session_start();

 $_SESSION['name'] = 'Arfan';

 $_SESSION['second_name'] = 'Haider';

echo 'My full name is '.$_SESSION['name'].$_SESSION['second_name'].'<br/>';

unset($_SESSION['second_name']);// unset the second_name session

echo 'My name is '.$_SESSION['name'].$_SESSION['second_name'].'<br/>';// work fine error popup

session_destroy();// Destroy all the session

echo $_SESSION['name']; // session is working here.
?>

As you can see at the end of the code session is also working why?

Answer 1

After using session_destroy(), the session cookie is removed and the session is no longer stored on the server. The values in $_SESSION may still be available, but they will not be on the next page load.

If you want to clear a session completely, you can use:

session_start();
session_destroy();
$_SESSION = array();
