TutorialZine has written a tutorial and shown us how to create a “Who is online” widget with PHP, MySQL and jQuery. It will display the number of visitors, currently viewing your site, and it will even be able to detect the country your visitors are from and display it in a slide out panel.

Having access to real time data on your site userbase is a dream to any webmaster. Tools like Google Analytics give a great perspective on your site’s reach, but lack the real time feel a simple widget like this can provide.

Requirements: PHP, MySQL, jQuery Framework
