Answer 1

your code should be like this based on logic..

ob_start();
session_start();
include_once 'dbconnect.php';
   if (!isset($_SESSION['user_id'])) // if the session is not set it will redirect to login.php
{
     header('Location: loigin.php');
}
   else{ // else redirect to profile.php
     header('Location: profile.php');
}
