we'll have to set a session variable after starting a
session as shown below
--------------------------------------------------
<?php
session_start();
if(isset($_SESSION['views']))
$_SESSION['views']=$_SESSION['views']+1;

else
$_SESSION['views']=1;
echo "Views=". $_SESSION['views'];
?>
--------------------------------------------------
it will set as well as increment the session variable
or we may simply echo a value to check whether a session is
started or not.
