Body
<p>Hi guys I have a simple membership based website where users log in and have their own profiles. I woudl like to be able to tell at any given point in time how many users or rather which users are currently logged into my website. </p> <p>Its a simple membership based system in php. One way I uderstand it creating a table in a db and storing login details there and session data as well but can this be done in some other way i.e. anyway to find out how many sessions have been started and all the unique users online.</p>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
