logging on

This tutorial is a continuation of our project called “How to Create a Social Networking Site Tutorial”. At this time we’re going to focus on creating login-logout system in a secure way using session. Logging in or signing in or on is the process by which individual access to a computer system is controlled by identifying and authenticating the user through the credentials presented by the user. To start in this tutorial, let’s create first a new PHP file called “session.php”. Then save it inside the inludes folder.
