how in php I count & show, visitors currently (now) view my website ?
Also how I refer to a webpage eg louravilla.html or louravilla.php as
detail.php?property=41&type=3&start=4 ?

If you google for "online users (http://www.google.com/search?q=online+users)" you can find many free scripts that you can add to your site to show how many users are online. Here are a few examples:
http://www.freeonlineusers.com/ (http://www.freeonlineusers.com/)
http://www.usersonline.com/ (http://www.usersonline.com/)
http://www.myonlineusers.com/ (http://www.myonlineusers.com/)
http://www.onlineuserscounter.com/ (http://www.onlineuserscounter.com/)
http://www.twospots.com/free-users-online-counter/ (http://www.twospots.com/free-users-online-counter/)

Good luck!
