Sort thread by results from Query

[DuNkLeArChOn]

Hey ,

I use vBulletin V 4.1.1 and have some problems with the sorting. I show in my threadbit the time&date of the modification of the first post of each thread.

here is the forumdisplay:

"?nderung" = "modification" .. its german, i'am sorry

I have do this with the help of these plugin :

ob_start(); 
/*** CONTENT ***************************************************************/ 
  $firstthreadabfrage = $vbulletin->db->query("SELECT firstpostid FROM " . TABLE_PREFIX . "thread WHERE threadid = '" . intval($thread['threadid']) . "'");  // Query, firstpostid anfordern 
    $firstthreadabfragearray = array();  
        while($trow = $db->fetch_array($firstthreadabfrage))  
            {  
            $firstthreadabfragearray["$trow[id]"] = $trow[firstpostid];  
            } 
         
        for ($x = 0; $x < sizeof($firstthreadabfragearray); ++$x)  
            { 
             $fpid = current($firstthreadabfragearray); 
//             echo $fpid." / ";                                // Kontrollausgabe 
            } 
//- - - - - - - - - - - - - - -  
$editabfrage = $vbulletin->db->query("SELECT dateline FROM " . TABLE_PREFIX . "editlog WHERE postid='$fpid'");  // Query, edit-datum anfordern 
    $editabfragearray = array();  
        while($erow = $db->fetch_array($editabfrage))  
            {  
            $editabfragearray["$erow[id]"] = $erow[dateline];           
            }  

for ($x = 0; $x < sizeof($editabfragearray); ++$x)            // Ausgabe des Datums + Uhrzeit 
    { 
    $datum = date("d.m.Y",current($editabfragearray)); 
    $uhrzeit = date("H:i",current($editabfragearray)); 
    echo $datum," - ",$uhrzeit," Uhr";     
    }   
/***************************************************************************/     
    $includedphp = ob_get_contents(); 
  ob_end_clean(); 

vB_Template::preRegister('threadbit',array('includedphp' => $includedphp));

but my problem is to sort the Threads depending on this modification-date ... i don't know where i can find the sort-functions in the PHP-Files to edit them :erm:
