php - 根据数组数据动态生成手风琴

问题描述

我正在阅读 mysql 以提取给定特定 ID 的一组数据，这会向我的脚本返回一个数组。那是容易的一点。这里的示例存储在一个名为 $history 的数组中

Array ( [serviceID] => 1 [VesselTag] => 1000001 [component] => Engine 1 [item] => Caterpillar [serial] => 123456 [comment] => Something in here like this [parts] => Oil [lat] => 50.38313740 [longitude] => -4.03461360 [engineer] => 27 [date] => 2019-05-30 19:25:56 ) 
Array ( [serviceID] => 2 [VesselTag] => 1000001 [component] => Engine 2 [item] => Caterpillar [serial] => 677889 [comment] => Did a full overhaul of top section replaced everything [parts] => everything [lat] => 50.38309180 [longitude] => -4.03468820 [engineer] => 27 [date] => 2019-05-30 19:27:29 ) 
Array ( [serviceID] => 3 [VesselTag] => 1000001 [component] => Engine 1 [item] => Caterpillar [serial] => 123456 [comment] => This seems quite usable [parts] => Oil [lat] => 50.38345892 [longitude] => -4.03475649 [engineer] => 27 [date] => 2019-05-30 19:29:23 )

我现在想做的是根据列表中的 [component] 生成一个手风琴'card-body' 对卡片进行分组。有时数组可能有更多或更少，因此将显示 0 到 7 张卡片 [组件]。

<div class="card">
  <div class="card-header">
    <a class="card-link" data-toggle="collapse" href="#collapseOne">
        $array[Component]  **<--- Guessing this would be from a ```foreach``` or ```while``` loop???**
    </a>
  </div>
  <div id="collapseOne" class="collapse" data-parent="#accordion">
    <div class="card-body">
      <?php **THIS IS WHERE I WILL DISPLAY THE ROWS OF DATA ASSOCIATED TO THE [component] IN QUESTION ?>**
    </div>
  </div>
</div>

我真的很难弄清楚要使用哪个循环，并且能够通过 [组件] 来驱动它。

它在做我的头......

解决方案

在看了很长一段时间不同的文章之后，我似乎想出了一些可行的方法......我认为它相对有效，但很高兴有人告诉我其他情况......

<div id="accordion">
    <?php $newArray=array();
            foreach($history as $val){
                $key=$val['component'];
                $grouped[$key][]=$val;
            }
            foreach($grouped as $group){?>
                <div class="card">
                    <div class="card-header">
                        <a class="card-link" data-toggle="collapse" href="#<?php echo str_replace(' ', '',$group[0]['component']); ?>">
                            <?php echo $group[0]['component']; ?>
                        </a>
                    </div>
                    <div id="<?php echo str_replace(' ', '',$group[0]['component']); ?>" class="collapse" data-parent="#accordion">
                        <div class="card-body">
                            <?php foreach ($group as $occurance){
                                echo $occurance['date'] . ' - ' . $occurance['comment'] . ' - ' . $occurance['parts'] . ' - ' . $occurance['engineer'];
                                echo '<br>';
                                } ?>
                        </div>
                    </div>
                </div>
        <?php }?>
</div>
