PHP page not updating unless I press CTRL + F5

Question

I have normal php project in which each and every page not updating unless I press CTRL+F5.

Now biggest issues is I can not press CTRL+F5 on logout.php where I destroy my session. Hence again I redirect it to login. Session is getting destroy and redirecting to login page but it'll not update unless I press CTRL+F5.

logout.php

   $_SESSION['user_type']       ='';
   $_SESSION['balance']         ='';
   unset($_SESSION['balance']);
   unset($_SESSION['user_type']);
   session_destroy();
   echo '<script>window.location.href="login.php"</script>';
   exit(0);

Why are you using a JS redirect instead of PHP's `header()` ?? — Shankar Narayana Damodaran, Feb 27 '14 at 08:16
If user has JS turned off, `` will just fail to redirect, consider using `header()` instead — Mr. Alien, Feb 27 '14 at 08:16
Also, it seems like buffer issue, take a look at `ob_start()` and `ob_flush` — Mr. Alien, Feb 27 '14 at 08:17
Mr. Shankar i tried using both JS AND header() it is redirecting but to login.php...and on login.php i'm print_r($_SESSION). this ll show session for 1st time and if i press CTRL+F5 it ll display blank array — yudi, Feb 27 '14 at 08:19
I think it is cache. You need to disable HTML caching. http://stackoverflow.com/questions/404617/disabling-the-browser-cache-in-php-or-using-javascript — Bogdan Burym, Feb 27 '14 at 08:36

When you want to destroy a session you still need to place session_start(); at the top of your page, otherwise session won't be destroyed correctly, also i would rather use header(); to redirect to login page instead of js

header("location: login.php");

instead of echo '<script>window.location.href="login.php"</script>'; try using

header('location:login.php');

or

echo '<meta http-equiv="refresh" content="1;url=login.php">';

Echoing a `` refresh tag on its own is not good practice - this should be enclosed in a valid HTML document. – halfer Feb 05 '16 at 19:46

Use header('location:login.php'); to redirect you page after session_destroy();
