Start session after destroy php

Question

I have a logout file for my web application. I would like to create a session after the logout so that I can echo a logout success message. My logout code works but I am unable to create a new session after destroying the previous one.

What is the best way to do this, see code:

//LOGOUT.PHP
session_start(); 

//// unset all $_SESSION variables
session_regenerate_id();
session_unset();
session_destroy();

$_SESSION['logoutsuccess'] = 'You have successfully logged out.';
header("Location: /login/");
exit;


//LOGIN.PHP (ECHO SUCCESS MESSAGE)

if(isset($_SESSION['logoutsuccess']))
{
echo '<div class="success">'.$_SESSION['logoutsuccess'].'</div>'; 
unset($_SESSION['logoutsuccess']);
}

I would like to avoid passing variables in the url if possible.

Is there any good reason for doing the redirect? Why can't you show the success status on the logout page? — Billy ONeal, Oct 20 '11 at 22:54

Call session_start() again after session_destroy()?

This is the best approach for your specific question, but I still don't see why you don't just show the message on the LOGOUT.PHP page. – Watermark Studios Oct 20 '11 at 22:58
@WatermarkStudios I'm doing the same thing.. he's possibly doing the redirect to avoid form resubmission on refresh... http://stackoverflow.com/questions/6320113/how-to-prevent-form-resubmission-when-page-is-refreshed-via-php – Sarah Mar 18 '16 at 15:12

Just start a new session:

session_start();
session_destroy();
session_start();
$_SESSION['food'] = 'pizza';

Instead of trying to store it as a session variable, you could check the referer and check for /logout/

if(strpos($_SERVER['HTTP_REFERER'], 'logout')  !== false) {
  echo 'You have successfully logged out.';
}
