Storing a Session Variable
The correct way to store and retrieve session variables is to use the PHP $_SESSION variable:

<?php
session_start();
// store session data
$_SESSION['views']=1;
?>
<html>
<body>;
<?php
//retrieve session data
echo "Pageviews=". $_SESSION['views'];
?>
</body>
</html>

Output:

page views 1

<?php
session_start();
if(isset($_SESSION['views']))
$_SESSION['views']=$_SESSION['views']+1;
else
$_SESSION['views']=1;
echo "Views=". $_SESSION['views'];
?>

output:

In the example , we create a simple page-views counter. The isset() function checks if the

"views" variable has already been set. If "views" has been set, we can increment our counter. If

"views" doesn't exist, we create a "views" variable, and set it to 1:
