In one sentence, describe what the following article is about:

This should be an actual page you intend the visitor to see. If you already have a website, this should be the front facing PHP script (usually index.php). Basically, any PHP file that is accessible from the web and you want to use to update the counter. It's recommended to use require_once over include. This will tell the hit counter to update the counts. It's also necessary to get the current counts for display. You can choose to show either the total number of hits or only the unique hits. It can be embedded anywhere HTML it output by the PHP script. Your hit counters should now increment appropriately when you view your web page. If you keep refreshing, your total hit count will increase but your unique session count will stay the same. This is good.
Create a new file to use your hit counter. Include the file containing the HitCounter class. Call the views processor. Display your view counts. Test your hit counter.
