Answer 1

Have you got an session_start(); on the top?

Not tested but cant you do something like this:

session_start();
$_SESSION['userID'] = $user->id;
if( $_SESSION['userID'] == $user->id )
{  
    header('Location: /index.php');
}

I never have this Problem before, interesting

Answer 2

This was annoying as hell but I finally figured out a solution.

config.php i had: include 'session.php';

At the top of session.php, I had: session_start();

By moving session_start() to the top of the config.php file, viola...

Problem solved!

I had the same problem recently. I'm writting a customized MVC Website for school and, as everyone told, start_session() must be written in the very first lines of code.

My problem was THE LOCATION of "session_start()". It must be the first lines of your global controller, not the first lines of the view. $_SESSION was not accessible in controller's files because it was only initiated when the server render the view.

Then, I'm using session_write_close() after the header('location: xxx.php') call to keep session variables for the next request.

ex:

globalController.php :

//First line
session_start();
require_once('Model/Database.php');
require_once('Model/Shop/Client.php');
...

logonController.php:

...
//Users is validated and redirected.
$_SESSION['client'] = $client;
header('location: index.php');
session_write_close();

Hope it solved your problems.

I know this is an old toppic but I found the solution (for me). I've put a exit after the header.

$_SESSION['session'] = 'this is a session';
header('location: apage.php');
exit;

This works for me
