quite simply you could convert the two times to unixtime and then:
unixtime_logout - unixtime_login = seconds between login and logout

then you have only to convert the seconds to days/hours/minutes/seconds

you'll have a heck of a time getting determining when someone 'logged out'.
you'll have to come up with a scheme to do that...one that says here is a
significant gap in time, i suppose the last page visited was when they left
the site since the last log in.

do *you* ever log out of a site, or do you just leave? i certainly don't
bother to log out.

oh, you mean "a lot". "alot" isn't a word..."allot" is, however you
aren't assigning or setting anything aside in the context of the sentence.
but, i digress...

once you get all your stuff in place, here's a standard dateDiff
function...it's not much from there to get a function to say 'n day(s), n
hour(s), n minute(s)', if you need that. but, here's the basic function:

function dateDiff($firstDate, $secondDate, $interval = 'd')
{
$intervals = array(
'y' => (365.25 * 24 * 60 * 60) ,
'm' => (30 * 24 * 60 * 60) ,
'w' => (7 * 24 * 60 * 60) ,
'd' => (24 * 60 * 60) ,
'h' => (60 * 60) ,
'n' => 60 ,
's' => 1
);
return floor(abs($firstDate - $secondDate) / $intervals[$interval]);
}
