【问题描述】：

我在星期一有一组课程，它们在 5 个不同的房间进行。我想使用 div 根据位置在列中显示它们并按位置排序，开始。我得到的数据没有问题（找到在星期一运行的所有类），但它只是在一列中列出它，所以我的 foreach 数组不正确。这是$数据

$calendar = array();
foreach ($data as $row) {
    $calendar[$row[0]][] = $row;
}
foreach($calendar as $key => $row) {
       foreach($row as $field => $value) { 
           $recNew[$field][] = $value;
       }
}

这里是数组摘录

     [""]=> array(20) 
     {
     [0]=> array(1) {
     ["calendars"]=> array(9) {

        <div class="class">

    </div>
    <?php } ?>

这就是我得到的

可能需要位置作为此工作的关键。

【问题讨论】：

我不知道您的脚本是如何生成您需要的输出的，但如果是这样，将其内容保留在 css 中的位置浮动将解决您的问题。一般来说，如果你能用你的 php 获得正确的 html 结构，那么样式几乎可以是你想要的任何 css。
考虑旋转表格，使Studio 1, Studio 2,... 堆叠在一起，他们的班级向右出。编码和样式会更容易
您可以为该位置的阵列添加另一个层。会去"" => array( 0 => array( 'calendars' => array( 'Studio 2' => array "id"=> "742",...更容易for循环
是的，我在设置宽度的 div 上有一个左浮动，但我的问题出在脚本中，并让不同的位置在新列中开始。
@sloga：在你的代码中添加你的 $data 数组，我可以帮助你

标签： php multidimensional-array foreach

【解决方案1】：

您可以尝试使用html表格打印结果：

<?php 
$calendar = array();
foreach ($data as $row) 
{
    for($i=0;$i<count($row);$i++)
    {   if(!array_key_exists($row[$i]["calendars"]["location"], $calendar))     
            $calendar[$row[$i]["calendars"]["location"]] = array();
        array_push($calendar[$row[$i]["calendars"]["location"]], $row[$i]["calendars"]);
    }
}
?>
<table>
<tr>
<?php
foreach($calendar as $key => $row):
?>
<td>

<table>
<tr><td><?php echo $key;?></td></tr>
<?php 
foreach($row as $r):
?>
<tr><td><?php echo $r["title"]; ?></td></tr>
<?php endforeach;?>
</table>
</td>
<?php endforeach;?>
</tr>
</table>

甜蜜！我能够使用它并使用 div 和 css 进行设计。谢谢！
