坚持简单的PHP循环逻辑

Question

I have an array which can have any no. of elements in it. Now i want to loop this array and create design such that each li can have 15 elements inside it , next set of li will be created based of multiples of 15's elements.

Now my array has exact 15 elements and the code i am trying creating 2 li , which it should create only 1 li.

May be my logic is too bad or I am missing anything.

Here is my code:-

  <?php $result = array(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15); ?>
    <div class="slide">
    <?php $design = '<ul class="slides"><li><div class="MainSlider">';
        foreach($result as $key=>$row) 
        {
            $design .= '<div class="MainSliderPic">'.$key.'</div>';
            if(($key+1)% 15 == 0){
            $design .= '</div></li><li><div class="MainSlider">';
            }

            if(count($result) == $key+1){     
            $design .= '</div></li></ul>';
            }
        }
    echo $design;
    ?>
    </div>

Don't mix opening and closing of tags in your code. Do it separately where it belongs, e.g.

$design = '<ul class="slides">';
$n = 0;
foreach($result as $key=>$row) {
    if ($n == 0)
        $design .= '<li><div class="MainSlider">';

    $design .= '<div class="MainSliderPic">' . $key . '</div>';

    ++$n;
    if ($n == 15) {
        $design .= '</div></li>';
        $n = 0;
    }
}

$design .= '</ul>';
echo $design;
