Prevent back button after logging out

Adding the script below at the top of each PHP page will prevent user from using the back button after logging out.

<?php
session_start();

// Check if session is active or not
if(!isset($_SESSION['session_variable_here'])) { 
$_SESSION['session_variable_here']=NULL;

//Display message below if there is no more active session
echo "Sorry you are no longer active. Please <a href='index.php'>login</a> again.";
die();
}

else

//Your action here if session is active

}
?>

Description:

This simple program will allow you to connect to the MySQL database using the database information you entered on the text boxes.

I signed up in a free hosting service to test the codes. I created a MySQL database inside the free hosting service I signed up and used the database information to test the program.
