php - Foreach loop: split elements in groups of five and six -

-

i'm using foreach loop output images fetched instagram api. want split outputted images in groups of four , five , in addition add div element each group except last 1 2 div's should added, following structure:

<div class="group>     <div class="extra"> </div>     <img/>     <img/>     <img/>     <img/> </div> <!-- close group of 5 --> <div class="group>     <div class="extra"> </div>     <img/>     <img/>     <img/>     <img/>     <img/> </div> <!-- close group of 6 --> <div class="group>     <div class="extra"> </div>     <img/>     <img/>     <img/>     <div class="extra"> </div> </div> <!-- close group of 5 -->

by using modulus in loop i've manage group elements correct number of items in each group, but when try add div each group breaks counting , i'm no longer getting correct number of elements grouped together. code i'm using print out images (12 in total):

  <div class="group"> <!-- open group-wrapper -->    $count = 0;    foreach($decoded_results['data'] $item) {        if ($count  % 11 == 0 || $count % 11 == 5 ) {           echo '<div class="extra"> </div>';            echo '</div> <div class="group">';       }        echo '<a target="_blank" href=' .$link_url. '>';       echo '<div class="img-wrapper">';       echo '<img src="'.$image_link.'" /> </div> </a>';        $count++;      }

any suggestion how can achieved?

this enough point in correct direction:

<div class='group'>     <div class='extra'></div>     <?php     $i = 1;     $j = 1;     $step = 4;     $count = count($decoded_results['data']);     foreach($decoded_results['data'] $k => $v) {         ?>         <a target='_blank' href='<?php echo $v;?>'>             <div class='img-wrapper'>                 <img src='<?php echo $v;?>' />             </div>         </a>         <?php         if (($j % $step) == 0 && $i < $count) {             ?>         </div>         <div class='group'>             <div class="extra"></div>             <?php             $step = ($step == 4) ? 5: 4;             $j = 0;         }         $j++;            $i++;     }     ?>     <div class='extra'></div> </div>

on side note should aware having div (block element) inside a (inline element) isn't semantic html, still accepted nowadays. tend avoid , can using css.
