How do I continue a session from one page to another with PHP

If your PHP setup is clear (session writing ok) and cookie normally sent to browser (and preserved), you should be able to do something like this

On first page :

session_start();
$_SESSION['userName'] = 'Root';

On a second page :

session_start();
if(isset($_SESSION['userName'])) {
  echo "Your session is running " . $_SESSION['userName'];
}

Be careful session_start() must be called before any output is sent, so if you had to use the @ for session_start it can hide warnings.

As these are warnings, if given example doesn’t work try to add this before calling session_start :

error_reporting(E_ALL);
