I want to have an Online user counter but something which performs real time. I mean when someone comes in, the counter updates, or when someone leaves the site, the counter decrease.
I can’t find anything like this on net. Is there any script for this ?
You could probably keep a list of all sessions in a database and update the “online time” every time someone hits a page. Then check how many sessions were updated in the last x minutes. However, this won’t be very real time: depending on the amount of minutes you defined it will be a little bit off.
Even Google Analytics (the new real time version) gets it wrong sometimes. Don’t worry too much if you can’t get it right either. 😉
