How to get the timespan a visitor stays on site before bouncing away?

**yangyang** · Apr 29th, 2008, 2:07 am

Trying to build a cute little php site statistics script, now I'm stuck with getting the average visiting time on site.

How to do that? I'm using JS badge.

HTTP is stateless, if that is the case how the server knows when the visitor navigates away? JS onunload?

I am sure he's building and wanting to use his own script for a reason.

yangyang, I'm not a programmer so I don't know, I am not sure there's any programmers here to help but hopefully there is.

I'm no coder either, but this might point you in the right direction:

Helps. Thanks.

The apache access logs can be analyzed for average on-site time, how does the stats program do that? e.g. weblog expert.

This way may help you on php
1. Make img.php with param opt:
opt=[0, 1] <=> [visited, leaved];
variable:

if($_SESSION['visited']=='') $_SESSION['visited']=time();
$opt=$_REQUEST['opt'];
$IP=$_SERVER['REMOTE_ADDR'];

[/QUOTE][/QUOTE] store 3 var abow to table state(ip, loggedtime, opt)
2. make cron.php run cron each 1 minute to do.
each $IP

if($opt==1 && (time()-lastcheck)>60))
{
make a row in table logging(ip, onlinetime, loggedtime)
del row with that ip
}

3. in each page of site insertcode

4. JS Code

funciton ols(id)
{
imgs=new Image();
imgs.src="your_link_site/yourpath/img.php?opt="+id;
return true;
}

make yourseft code and check for free

There is no way. The users browser does not send anything to a site its leaving.

The only thing you can do is use a third party like google analytics which will know when the user has gone to another site, if they also use analytics. Its also free.

Why can google do the impossible then? There must be a way to do it. I'm assuming it is something to do with JS, but I am no coder (html and basic php

).

Did you check google search code?
If you did, you can find that: my code is possible.
