In Listing 5.39 it must be PRIMARY KEY (login_time) and not (period_of_time).

The field 'refer' in the SQL is not necessary because the result is always the server the application is installed
on.
This is also the reason to erase the entry 'localhost' in the sample recordset.

The listing to show month and day of month is:
<TR>
<?php

The listing to get the visits sorted by hour is (beginning at row $hour_actually = ...):
$hour_actually = date(G, $total_end_time);
// count hits
// Zaehle Treffer
$overall_h = mysql_num_rows($Select_database);
$t_hour = $hour_actually + 1;
// result is midnight
// Wenn das Ergebnis 24 Uhr ist
if ($t_hour == 24) {
$t_hour = 0;
}
?>

The array $overall[count] is replaced in row 2 and 6 by $overall_h
Page 471
The array $overall[count] is replaced in row 7 by $overall_h

This listing gets the hits for a path. After this the loaded pages are counted.
// get the highest score of a path
// Ermitteln der hoechsten Trefferzahl eines Pfades
$query_score = "SELECT hit FROM $tbl_path ORDER BY hit DESC";
$result_score = mysql_query($query_score) or die($stats_select . $tbl_path . $stats_result);

// get the loaded pages
// Ermitteln der genutzten/geladenen Seiten
$query = "SELECT path, hit FROM $tbl_path ORDER BY hit DESC";
$result = mysql_query($query) or die($stats_select . $tbl_path . $stats_result);

This listing provides a new window:
// get RIPE
// Wenn User ueber RIPE ...
echo ("<A HREF=\"javascript:new_browser('".$cmd.$ip."&submit=Anfrage+senden')\">more...</A></TD>");
// get INTERNIC
// Wenn User ueber INTERNIC ...

The rows $server=... and $domain=... are to be erased.
$host_adress is to be replaced by $host.
Before getting the value for $lang execute the following lines:
if ( empty($host)) {
$host = $ip;
}
$lang gets its value now in a different way:
$lang=substr(getenv('HTTP_ACCEPT_LANGUAGE'),0,5);
if (substr($lang,1,1)!="-" || substr($lang,2,1)!="-")
{
$lang = substr($lang,0,2);
}
The following code is also updated:
// analyse the domain o get the ending
// Zerlege die domain so, dass nur die Endung nach dem letzten Punkt
// uebrig bleibt
if ($host == "localhost") {
$country="other";
} else {
$country=substr(strrchr($host,"."),1);
}

The row $domain_server = ... is to be erased.
To update the table countersys and to insert a recordset into table stats looks now like this:
// check is OS is already in DB
// Pruefe, ob OS schon auf der Datenbank oder neu ist
$Select_os = "SELECT type FROM $tbl_countersys WHERE (var = '$os')";
$result_os = mysql_query($Select_os) or die($stats_select . $tbl_countersys . $stats_result);
$number_os = mysql_num_rows($result_os);
if ($number_os > 0) {
// update table countersys
// Updaten von countersys
$os_upd = "UPDATE $tbl_countersys ";
$os_upd .= "SET count=count+1 ";
$os_upd .= "WHERE (var='$os' AND type='os')";
mysql_query($os_upd) or die($stats_update . $tbl_countersys . $stats_result);
} else {
// insert new OS into table countersys
// Einfuegen eines neuen OS in countersys
$os_upd_other = "UPDATE $tbl_countersys ";
$os_upd_other .= "SET count=count+1 ";
$os_upd_other .= "WHERE (var='Other' AND type='os')";
mysql_query($os_upd_other) or die($stats_update . $tbl_countersys . $stats_result);
}
// check if browser is already in db
// Pruefe, ob Browser schon auf der Datenbank oder neu ist

$number_browser = mysql_num_rows($result_browser);
if ($number_browser > 0) {
// update table countersys
// Updaten von countersys
$browser_upd = "UPDATE $tbl_countersys ";
$browser_upd .= "SET count=count+1 ";
$browser_upd .= "WHERE (var='$browser' AND type='browser')";

The value must be 3599 instead of 3559:
// calculate the time to get xx:59:59
// Berechne die Zeit, dass sich der Wert xx:59:59 ergibt
$end_hour = $full_hour + 3599;
