With this library you can add indicators to your navigation bar with a little PHP code.
The indicators update automatically at a configurable interval. The entire page is not reloaded, but only the display of the indicator is updated. The rest of your page remains unchanged, so that the update does not interrupt your users in their work.
The whole thing works with AJAX technology, but you don't have to worry about the technical details: We've packaged everything so that you can use the functionality with very little code, and still have lots of flexibility because you can use PHP to determine the values to display.
