divisione contenuti su due colonne

[rocco.mod]

salve gente ho un problema e non riesco a trovare una soluzione, io dal db estraggo le FAQ,domanda e risposta , sino che le caricavo in ogni singola colonna andava e va tutto perfettamente, ma ho deciso di fare su due colonne e sto esaurendo, ho fatto cosi:

$colonne = 2; 
$tot_righe = $num_record/$colonne; 
$i_x = 0; 
$x_x = 0; 
$k_x = 0; 
$cell_width = floor(100/$colonne); 
$DB->connect();
$controllo_colonne = mysql_query("select * from knowledgebase_cat  where enable ='1' and kat_kvisible ='1'   ");
$num_record = @mysql_num_rows($controllo_colonne); 

echo 
"<table class='tabhome' style='width:100%;' border='0' cellspacing='0' cellpadding='0'> <tr>";  

      
 while($array = mysql_fetch_array($controllo_colonne)){ 
$i_x++; 
$k_x++; 
$x_x++; 
echo"<td>";

$DB->connect();
$result_cat_know = mysql_query("select * from knowledgebase_cat  where enable =1 and kat_kvisible =1  order by id desc ");
if (@mysql_num_rows($result_cat_know)>0){ 
while($array=mysql_fetch_array($result_cat_know)){?>

<table class="knowtitle" border ="0"  cellpadding="0" cellspacing="0" style="width:100%;" >
  <tr>
    <td><table class = "tablecatknow" border ="0" cellpadding="0" cellspacing="0">
        <tr>
          <td class ="imagecategoryknow"><?php echo"[img]$path_site/template/$template/images/icone_mini/icon_folderyellow.gif[/img]";?></td>
          <td class ="categoryknow"><?php echo"[url='$path_site/index.php?page=$page&viewcategory_knowledgebase=viewcategory&id_cat=".$array[']".$array['nome']."[/url]";?> <span class ="numerarticle">(<?php echo totale($array['id']);?>)</span></td>
          <td class ="rssiconknow"></td>
        </tr>
      </table></td>
  </tr>
  <tr>
    <td><?php
$id = $array['id'];
$title = $array['nome'];
$result_know = mysql_query("select * from knowledgebase where  k_cat ='".$array['id']."' and  visible ='1'  and enable ='1' order by id desc limit 3" );
?>
      <table class = "ultimiarticoliknow" border ="0" cellpadding="0" cellspacing="0" onMouseOver="javascript:this.className='navitem'" onMouseOut="javascript:this.className ='navitemhover'" style="width:100%;">
        <?php
if( @mysql_num_rows($result_know)>0){
while($array=mysql_fetch_array($result_know)){  ?>
        <tr>
          <td class ="imagearticolokn"><?php echo"[img]$path_site/template/$template/images/icone_mini/icon_topicyellow.gif[/img]";?></td>
          <td class="articoloknow"><?php echo"[url='$path_site/index.php?page=$page&viewarticle=viewarticle_knowledgebase&id_article=".$array[']".$array['domanda']."[/url]";?></td>
        </tr>
        <?php
    }
    }else{?>
        <tr>
          <td class ="imagearticolokn"></td>
          <td class="articoloknow"><div class="textsfondo"><?php echo _NO_ARTICLE_KNOWLDG ; ?></div></td>
        </tr>
        <?php    }?>
      </table></td>
  </tr>
</table>
<?php 
}
}else{ 
echo"<div class='textsfondo'>"._NO_CATEGORY_KNOWLDG."</div>";
 }
echo"</td>";
if($i_x == $colonne) { 

echo"</tr>"; 

if ($i_x == $colonne && (($x_x/$colonne) != $tot_righe)) { 
echo"<tr>";
   } 
$i_x = 0; 
 } 
} 
if ($colonne <= $x_x){ 
if (($k_x%$colonne) != 0){ 
$indice = $k_x; 
$indice++; 
if(($indice%$colonne) == 0 ){ 
echo'</tr>';  
   } 
 }         
} else{ 

echo '</tr>';              
} 
echo '</table>';

adesso mi da le due colonne ,ma mi scarica il tutto ripetutamente per 3 volte dove toppo?
