getting session variable even after session destroy

Question

I am newbie in php. I can not under stand a thing that session variable is outputting even after session_destroy() and session_unset().Here is my simple code for test

`session_start();
 SESSION['name']='sovon';
 session_destroy();
 session_unset($_SESSION['name']);
 echo $_SESSION['name'];

`

The output is 'sovon'. My question what is session_destroy() and session_unset() doing here and whats the difference between them? Oh! when I am deleting session_destroy() that variable is getting unset. why?

Answer 1

I got it faisal, session_distroy is destroying session if its created in other pages. If the session variable created on the same page then it will be remain. The best practice is to null the session variable after session distroY $_SESSION = NULL;

Like I am using in logout,

session_start();
session_distory();
$_SESSION = NULL;
header('Location: Login.php');

I think this help you.
