Delete record onExit

[renesis]

Hi all.
Assume I want to track somehow who is online at my website.
First, what I have done is when someone enters the index.php, a new record is written with his IP.
But I still haven't found a way to delete this record when the user exits the website either by closing the browser or visiting another website.
Note that there is not a login function. The code only checks for IP and if valid, the user proceeds.
Any ideas?
Many thanks!

You'll never know. About the best thing you can do is implement the same thing PHP does to delete expired sessions. Have a look every now and then at the records (wherever they're written) and delete those that haven't been touched in a certain length of time.

Exactly . Imagine someone having a power cut ? Or someone to tear off an Ethernet cable ?

There will be no event process, no onExit or anything like that, he's just gone 🙂
