well that gives you a good example of using session variables. What exactly do you want to use session variables for?

I know how to work with session variables. I wanted to use session id’s to keep track of a user surfing the website, for instance, how many times has that user viewed that page and so on.

if you want to count unique hits on a certain page, or even a site, you could register a session variable that indicates whether it’s the user’s first visit to the page or not, and incrementing the counter based on that, therefore counting unique hits. Look at the code:

```php
<?php

session_start();

if ( !isset( $_SESSION['visited'] ) ) // if the variable 'visited' has not been set
{
$_SESSION['visited'] = 1; // register the session variable 'visited'
/*

increment counter here, be it mysql, xml, flat file, etc..

*/
}

// ...

```

Using that, you know you’re adding 1 to the counter only once per user session 🙂
