logout.php

 <?php

Answer 1

1. Make sure the file is on same server.
2. Write this code on the very top of everything else.

3. Additionally use this code

   session_unset();
   session_write_close();
   

4. session_destroy only destroys session on server end not the cookies, make sure you are not using cookies, if yes then see below code

To Set cookie

setcookie("cookieName", $value, time()+3600);  

To Unset Cookie

setcookie("cookieName", $value, time()-36000);
