I am trying to check whether a user is logged in or not on the index.php page. If user is not logged in I want to redirect the user to login.php page.

Below is error log:

> PHP Warning: Cannot modify header information - headers already sent
> by (output started at

Kindly check my session.php code:

<?php
//Start session
session_start();
//Check whether the session variable SESS_MEMBER_ID is present or not
if (!isset($_SESSION['id']) || (trim($_SESSION['id']) == '')) {
    header('location: login.php');
    exit();
}
$session_id=$_SESSION['id'];
?>

Kindly check the line no. 2 of my index.php:

<?php include('session.php'); ?>

Whats wrong in my code ? I would really appreciate if anyone can guide to to solve these errors.

Thanks in advance.

The problem is that you are sending the DOCTYPE on the first line, before the session starts.

<!DOCTYPE html> 
<?php include('session.php'); ?> 
<?php include('dbcon.php'); ?> 
<html lang="en">

Change to 

<?php include('session.php'); ?> 
<!DOCTYPE html> 
<?php include('dbcon.php'); ?> 
<html lang="en">

Make sure the include is the first line

Do you use header(); before session_start(); in index.php ??

If you do that session_start must be in top of the page or try to remove it from session.php to top of index.php
