On our server the Apache logs have more entries for Red Alert and various
other IIS worms than real user requests. I have completely given up on them
:-(

Here's the latest - the stats I am still working on are hostname, referring
page, and ISP

suggestions welcome!

You have some good ideas, but the code is really hard to follow, try to
structure it a bit more.
also, just put it in one file, and do an include() on it from your other
pages.

Also, if I may, don't log the host name, this lookup can add considerable
delay, proccess that when you spawn a bg proccess.

If I may also, don't keep diving into functions getenv, use a simple $var =
.... and reference the $var instead, this keeps it easy to modify your code.

just my 2 cents

Re: How to log visitors using PHP?

no doubt, the code is a mess - this is just a beta hack - will create functions
and clean up when I can first get everything to print to screen...

You say this will result in a delay:

<?php
function gethost($visip) {
$host = `host $visip`;
return (($host ? end ( explode (' ', $host)) : $visip));
}
print gethost($visip) ;
?>

Do you suggest doing this for all visitor IPs at the end of the day (2:00am) in
a batch process?

You mean like this:

$var = getenv("HTTP_US ER_AGENT")

<?php print $visip;
// identify browser
if((ereg("Nav", $var)) || (ereg("Gold", $var)) || (ereg("X11", $var)) ||
(ereg("Mozilla" , $var))

and so on throughout the script?
....
$visbrow = "Netscape";
elseif(ereg("Op era", getenv("HTTP_US ER_AGENT")))
$visbrow = "Opera";
elseif(ereg("MS IE", getenv("HTTP_US ER_AGENT")))
$visbrow = "MSIE";
elseif(ereg("Ly nx", getenv("HTTP_US ER_AGENT")))
$visbrow = "Lynx";
elseif(ereg("We bTV", getenv("HTTP_US ER_AGENT")))
$visbrow = "WebTV";
elseif(ereg("Ko nqueror", getenv("HTTP_US ER_AGENT")))
$visbrow = "Konqueror" ;
...
?>

Re: How to log visitors using PHP?

This prints all the data I'm after to the screen. One improvement I'd like to
make is to identify the Windows OS version - so it will report "Windows XP" or
"Windows 2000", or whatever, instead of just "Windows".

Note - assigning getenv("HTTP_US ER_AGENT") to $var did not work.

The next step is to get this to write everything nicely to a file that can be
easily batch uploaded into MySql - and prior to doing so, run a batch process to
get the host name of all the logged IPs. Once issue with that idea, however, is
that most folks are using DHCP so the IP may be stale when the process is run -
but I suppose it will return the same info regardless - unless the IP is now
unassigned...

yes do it in a batch instead of live

$host = gethostbyaddr($ visp); // built in php function

Do you mean that I don't need to embed the code in an html page? So, I can have
a file in public_html named "visistats. php? and then just call a function from
that file into index.php, or whatever.php? What does teh syntax look like?
What if someone trys to access http://www.domain.com/visistats.php?

Worse, I work at a large university. The server is connected via a gigabit
link to a network with several thousands poorly protected Windows boxes.
