PHP MySQL Echo计数

Question

我试图使按钮每行回显5，并且对于每一行，它们将被元素包裹。

我遇到的问题是回声，回声没有发生我的想法。

由<div class="section group"></div>包装的所需结果 （每5个span_1_of_5 ）

<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>

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++;
    }
    ?>

PHP的输出 （不是所需的结果）

<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>

我不明白为什么会这样，任何启蒙都会很棒。 谢谢

Answer 1

更改：

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

至：

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

也改变：

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

至：

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

我觉得它更容易。 几个旁注：

1. 如果这是新代码，最好使用mysqli / Pdo。
2. 总是使用<?php而不是短代码<? 。
3. 始终使索引字符串： $row5x['item_id'];

Answer 2

$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++;
    }
    ?>
