Can you try this, Added $Reset variable so every loop >10 it reset the count

    <?php
    $listings = explode("<hr/>", $list);
    $numberOfListings = count($listings);
    $Reset =1;
    for($i = 0; $i < $numberOfListings; ++$i) 
    {
        if ($Reset == 4)
        { ?> 

   <some ad script runs in>

   <?php } if ($Reset == 9) { ?> 

   <some ad script runs in>

    <?php }
         echo $listings[$i] . "<hr/>";

         if($Reset>10){
                $Reset =1;
          }
          $Reset++;

    }
    ?>
