Session variable stores the information about a user that variable will be availbale to all pages and we can handle the login track using the session concept
Session is time duration when the user start to browse a webpage and it will be live until the page close.
in php we will use the ‘session_start();’ function at the begining of a php page
for example
$_SESSION[‘mydoubts’]=’somevalue’;
in each page we can check the session is set or not using the below script
if(isset($_SESSION[‘mydoubts’]))
{
// shows the page you want to display
}
else
{
// redirect home page.
}
For destorying the session
session_destroy()
