Merhaba, kodum düzgün çalışıyor ama stoğu olmayan İstanbul Depo'da YOK yazmıyor.

<li class="d-flex justify-content-between mb-3 pb-3 border-bottom">
   <span class="text-dark fw-medium">Adana Depo 1</span>
   <? if ($anka): ?>
   <span class="text-muted">
   <?php 
      if ($urun['anka'] >  "0") {
          echo 'VAR';
      }else{
          echo 'YOK';
      }
      ?>						    
   </span>
   <? endif ?>
</li>


<li class="d-flex justify-content-between mb-3 pb-3 border-bottom">
   <span class="text-dark fw-medium">Adana Depo 2</span>
   <? if ($a01): ?>
   <span class="text-muted">
   <?php 
      if ($urun['a01'] >  "0") {
          echo 'VAR';
      }else{
          echo 'YOK';
      }
      ?>						    
   </span>
   <? endif ?>
</li>


<li class="d-flex justify-content-between mb-3 pb-3 border-bottom">
   <span class="text-dark fw-medium">İstanbul Depo</span>
   <? if ($a34): ?>
   <span class="text-muted">
   <?php 
      if ($urun['a34'] >  "0") {
          echo 'VAR';
      }else{
          echo 'YOK';
      }
      ?>						    
   </span>
   <? endif ?>
</li>

Bu sorun neyden kaynaklı olabilir
