To define click as visit?

[omen]

I have code for tracking time of visitor. I have the fillowing function:

PHP Code:
function olduser($visitID)
{
$now = time();
$visitData = getVisit($visitID);
if ( ! $visitData )
{ return newuser();}
$visitData ['totalClicks']++;
if ( ($visitData ['lastVisit'] + $GLOBALS ['slength']) > $now)
{
$visitData ['totalDuration'] += ($now - $visitData ['lastVisit']);
}
else
{
$visitData ['numVisits']++;
}

$visitData ['lastVisit']=$now;
updateVisit ($visitData);

Here is the whole code to track visitor:


PHP Code:
<?


$db = "data/testdb";
$dbres = sqlite_open ($db, 0666,$error);

if (!is_int ($field))
if (!is_resource ($dbres))
{
die ("sqlite error:$error");
}

$GLOBALS['slength']= 300;
$GLOBALS['dbres'] = connect ("data/testdb");
$GLOBALS['visitID']= $_COOKIE['cookname'];
$GLOBALS['userStats'];

if (empty($visitID) )

{
$userStats=newuser();
print "Welcome, first time user!";
}

else
{
print "Welcome back, $visitID!";
$userStats=olduser($visitID);
}

function newuser()
{
$visitData = array
(
'FirstVisit'=>time(),
'LastVisit'=>time(), -- This message may have been cut off and the rest will only be shown to members. To become a member, click here --
