Simple login using php (part 3)

Here i am going to discuss about the check.php.

This php page will check if the user is logged in or not . If not it will redirect the user to login page.

<?php

//session starts here

session_start();

//check if session is registered

if(session_is_registered('userid'))

{

//if registered display the content you would like to show

echo 'Hello you are logged in.';

}

else{

//if session variable is not registere send back user to login page

header( "Location: http://login.html" );

}

?>
