PHP MySQL的回聲計數

我正在嘗試使按鈕回顯5每行，併爲每行他們將被一個元素包裹。PHP MySQL的回聲計數

我遇到的問題是回聲時，回聲沒有發生，我以爲會發生。

期望的結果（每5 span_1_of_5）由<div class="section group"></div>

<div class="section group"> 

    <div class="col span_1_of_5"> 
     <div class='button_epos_a button_epos_a-border'> 
      <div class='button_epos_a_content'> 
       Button 
      </div> 
     </div> 
    </div> 

    <div class="col span_1_of_5"> 
     <div class='button_epos_a button_epos_a-border'> 
      <div class='button_epos_a_content'> 
       Button 
      </div> 
     </div> 
    </div> 

    <div class="col span_1_of_5"> 
     <div class='button_epos_a button_epos_a-border'> 
      <div class='button_epos_a_content'> 
       Button 
      </div> 
     </div> 
    </div> 

    <div class="col span_1_of_5"> 
     <div class='button_epos_a button_epos_a-border'> 
      <div class='button_epos_a_content'> 
       Button 
      </div> 
     </div> 
    </div> 

    <div class="col span_1_of_5"> 
     <div class='button_epos_a button_epos_a-border'> 
      <div class='button_epos_a_content'> 
       Button 
      </div> 
     </div> 
    </div> 

</div> 


<div class="section group"> 

    <div class="col span_1_of_5"> 
     <div class='button_epos_a button_epos_a-border'> 
      <div class='button_epos_a_content'> 
       Button 
      </div> 
     </div> 
    </div> 

    <div class="col span_1_of_5"> 
     <div class='button_epos_a button_epos_a-border'> 
      <div class='button_epos_a_content'> 
       Button 
      </div> 
     </div> 
    </div> 

    <div class="col span_1_of_5"> 
     <div class='button_epos_a button_epos_a-border'> 
      <div class='button_epos_a_content'> 
       Button 
      </div> 
     </div> 
    </div> 

    <div class="col span_1_of_5"> 
     <div class='button_epos_a button_epos_a-border'> 
      <div class='button_epos_a_content'> 
       Button 
      </div> 
     </div> 
    </div> 

    <div class="col span_1_of_5"> 
     <div class='button_epos_a button_epos_a-border'> 
      <div class='button_epos_a_content'> 
       Button 
      </div> 
     </div> 
    </div> 

</div>

包裹的PHP

$itemCount = 0;  

    while ($row5x = mysql_fetch_array($result5x)) { 

    $item_id = $row5x[item_id]; 
    $item_title = $row5x[item_title]; 

     if ($itemCount==0 || $itemCount%5===0) { echo "<div class='section group'>"; }  
    ?> 

    <div class="col span_1_of_5"> 
     <div class='button_epos_a button_epos_a-border'> 
      <div class='button_epos_a_content'> 
       <? echo $item_title; ?> 
      </div> 
     </div> 
    </div> 

    <? 
    if ($itemCount%5===0) { echo "</div>"; }  
    $itemCount++; 
    } 
    ?>

從PHP（未預期的結果）輸出

<div class='section group'>  

    <div class="col span_1_of_5"> 
     <div class='button_epos_a button_epos_a-border'> 
      <div class='button_epos_a_content'> 
       Coffee   
      </div> 
     </div> 
    </div> 

</div>  

<div class="col span_1_of_5"> 
    <div class='button_epos_a button_epos_a-border'> 
     <div class='button_epos_a_content'> 
      sdsd    
     </div> 
    </div> 
</div> 


<div class="col span_1_of_5"> 
    <div class='button_epos_a button_epos_a-border'> 
     <div class='button_epos_a_content'> 
      cccc    
     </div> 
    </div> 
</div> 


<div class="col span_1_of_5"> 
    <div class='button_epos_a button_epos_a-border'> 
     <div class='button_epos_a_content'> 
      BBBB    
     </div> 
    </div> 
</div> 


<div class="col span_1_of_5"> 
    <div class='button_epos_a button_epos_a-border'> 
     <div class='button_epos_a_content'> 
      juice   
     </div> 
    </div> 
</div> 

<div class='section group'>  

    <div class="col span_1_of_5"> 
     <div class='button_epos_a button_epos_a-border'> 
      <div class='button_epos_a_content'> 
       juice2   
      </div> 
     </div> 
    </div> 

</div>

我不明白爲什麼會發生這種情況，任何啓蒙都會很棒。感謝

變化：

if ($itemCount==0 || $itemCount%5===0) { echo "<div class='section group'>"; }

要：

if ($itemCount==0) { echo "<div class='section group'>"; }

也隨之變化：

<? 
    if ($itemCount%5===0) { echo "</div>"; }  
    $itemCount++; 
} 
?>

要：

<?php 
    if ($itemCount===4) { echo "</div>"; $itemCount = 0;} else { $itemCount++;} 
} 
if ($itemCount !== 0) { echo '</div>';} 
?>

我認爲它更容易。附註：

如果這是新代碼，最好使用mysqli/Pdo代替。
始終使用<?php代替短代碼<?。
務必讓你的索引字符串：$row5x['item_id'];

是的，固定的問題，和側筆記已採取在船上，非常感謝。 – Derple

$itemCount = 0;  

    while ($row5x = mysql_fetch_array($result5x)) { 

    $item_id = $row5x[item_id]; 
    $item_title = $row5x[item_title]; 

     if ($itemCount==0 || $itemCount==5) { echo "<div class='section group'>"; }  
    ?> 

    <div class="col span_1_of_5"> 
     <div class='button_epos_a button_epos_a-border'> 
      <div class='button_epos_a_content'> 
       <? echo $item_title; ?> 
      </div> 
     </div> 
    </div> 

    <? 
    if ($itemCount==4 || $itemCount==9) { echo "</div>"; }  
    $itemCount++; 
    } 
    ?>
