Probably a bit of a dumb question but I just started learning php. I have to make some exercises and one of them is to make a php file that displays how often you have visited a page without closing your webbrowser (session variables). I managed to do quite so, but when I open the page I get the error: Notice: Undefined index: count in ... on line 5
PHP file:
<?php
session_start();
$_SESSION['count']++;
if($_SESSION['count'] == 0){
echo "You have not visited this page earlier yet since you closed your webbrowser";
} else {
echo "You have already visited this page " . $_SESSION['count'] . " times before you closed your webbrowser";
}
?>
