[Mediawiki-l] change {{NUMBEROFARTICLES}}

[Steffen Grimm]

Hello,
I've got a wiki abot a special theme. All pages, which doesn,t apply to the wiki are linked to wikipedia (with a template) But I want, that these pages aren't counted in {{NUMBEROFARTICLES}}. I've got pages in other namespaces, which should be counted, too.
This variable isn't working right, so I decided to change the code:
<? 
        include ('dbpass.php'); 
    @mysql_connect($dbhost, $dbuser, $dbpass); 
    @$x=mysql_select_db($dbdata); 
        if (empty($x)) { 
           echo "Fehler beim Verbinden mit dem Datenbankserver<br>"; 
           exit; 
        } 
    $sql = "SELECT page_namespace FROM page WHERE page_namespace = 0 OR page_namespace = 4;"; 
    $result  =  mysql_query($sql);

$a = 0;
while ($resuld = mysql_fetch_array($result, MYSQL_NUM)) {
   $a++;
}
    $sql = "SELECT page_namespace FROM page WHERE page_is_redirect > 0;"; 
    $result  =  mysql_query($sql);

$c = 0;
while ($resuld = mysql_fetch_array($result, MYSQL_NUM)) {
   $c++;
}
    $sql = "SELECT page_namespace FROM page WHERE page_len = 5;"; 
    $result  =  mysql_query($sql);

$d = 0;
while ($resuld = mysql_fetch_array($result, MYSQL_NUM)) {
   $d++;
}
$summe = $a + $b;
$summe -= $c + $d;
?> 
This code is working allright, but I don't know where to place it. Must I put it to initStats.inc in the maintenance-folder, or  in SpecialStatistics.php?
Please help me!! :-(
