Попробуйте, как это ... в виду:

<?php foreach ($categories as $key=>$value) { ?> 
     <div class="col-sm-3"> 
      <h5><?php echo $categories[$key]->categoriesName; ?></h5> 
      <?php if(count($categories[$key]->subs)>0) { ?> 
      <?php foreach ($categories[$key]->subs as $k=>$v) { ?> 
       <ul> 
        <li><a href="<?php echo base_url();?>member/detail"> 
         <?php echo $v->productName; ?></a></li> 
       </ul> 
      <?php } ?> 
      <?php } ?> 
     </div> 
<?php } ?> 

<div class="row" id="productMain"> 
    <div class="col-sm-4"> 
     <div id="mainImage"><img src="<?php echo base_url('upload/'.$details->photo);?>" 
     alt="" class="img-responsive">div> 
    </div> 
<?php if(count($details)>0){ 
    <div class="col-sm-4"> 
     <div class="box"> 
      <h1 class="text-center"><?php echo $details->productName;?></h1> 
      <p class="price"> 
       <?php echo $details->price;?> 
      </p> 
     </div> 
    </div> 
<?php } ?> 
</div>
