array_slice を使用して、シャッフルされた配列から最初の 9 つの値を選択します。

$sponsors = array_slice($sponsors, 0, 9);

foreach($sponsors as $company)
{
    echo'
       <div class="sponsor" title="Click to flip">
       <div class="sponsorFlip">
       <img src="img/sponsors/'.$company[0].'.png" alt="More about '.$company[0].'" />
       </div>
       <div class="sponsorData">
       <div class="sponsorDescription">'.$company[1].'</div>
       <div class="sponsorURL"><a href="'.$company[2].'">'.$company[2].'</a>
       </div>
       </div>
       </div>
      ';
}

array_sliceまたは_array_splice

注: どちらの機能にもわずかな違いがあります。マニュアルを見て、必要に応じて選択してください。
