我有多维数组，我得到这样的输出：

Array
(
    [Bukit Panjang LRT] => Array
        (
            [0] => Array
                (
                    [station_name] => Senja (BP13)
                )

            [1] => Array
                (
                    [station_name] => Ten Mile Junction (BP14)
                )
        )

    [Changi Airport Branch Line (CAL)] => Array
        (
            [2] => Array
                (
                    [station_name] => Changi Airport (CG2)
                )

            [3] => Array
                (
                    [station_name] => Expo (CG1 / DT35)
                )
        )
)

我的 foreach 循环：

$level_keys = array();
foreach ($mrtlrt_line as $k => $sub_array){
  $this_level = $sub_array['header_name'];
  $level_keys[$this_level][$k] = array('station_name' => $sub_array['station_name']);
}

我想像这样在 HTML 元素中显示值：

<h4>Bukit Panjang LRT</h4> <div>
    <label class="label_check">
        <input name="line" value="1" type="checkbox" />Senja (BP13
    </label>
    <label class="label_check">
        <input name="line" value="2" type="checkbox" />Ten Mile Junction (BP14)
    </label> </div>

<h4>Changi Airport Branch Line (CAL)</h4> <div>
    <label class="label_check">
        <input name="line" value="1" type="checkbox" />Changi Airport (CG2)
    </label>
    <label class="label_check">
        <input name="line" value="2" type="checkbox" />Expo (CG1 / DT35)
    </label> </div>

有什么想法或建议吗？谢谢。

试试这个代码

<?php
//Your array- `$mrtlrt_line`
foreach($mrtlrt_line as $key => $value)
{
   echo '<h4>',$key,'</h4><div>';
   foreach($value as $nkey=>$nval)
   {
      echo '<label class="label_check">';
      echo '<input name="line" value="1" type="checkbox" />',$nval;
      echo '</label>';
   }
   echo '</div>';
}

试试这个

    <?php
    foreach ($YourMulArr as $key => $subAry)
    {
        echo "<h4>" . $key . "</h4>"; 
        echo "<div>";
        foreach ($subAry as $k => $Ary)
        {
            echo "<label class='label_check'>";
            echo "<input name='line' value='" . $k+1 . "' type='checkbox' /> ". $Ary['station_name'];
            echo "</label>";
         }
         echo "</div>";
    }
    ?>

您必须从 php foreach 循环创建 html 并在其中注入数组值。看到这个代码

foreach ($mrtlrt_line as $k => $sub_array){

  $level_keys[$this_level][$k] = array('station_name' => $sub_array['station_name']);
  $level_keys[$this_level][$k+1] = array('station_name' => $sub_array['station_name']);

  echo '<h4>'.$sub_array['header_name'].'</h4> <div><label class="label_check"><input name="line" value="1" type="checkbox" />'.$level_keys[$this_level][$k].'</label><label class="label_check"><input name="line" value="2" type="checkbox" />'.$level_keys[$this_level][$k+1].'</label> </div>';

}

我希望您知道应该如何将数组注入到 html 中。

要扩展 swapnesh 的答案，您需要 2 个 foreach 循环。Foreach mrtlrt_line 您要循环遍历该数组中的内容。

您应该尽可能地将表示逻辑与业务逻辑分开。使用 alt php 语法是个人选择，但我主观上认为它使演示代码更易于阅读。

<?php foreach($mrtlrt_line as $key => $value): ?>
<?php /* interator */  $i = 0; ?>
    <h4><?php echo $key; ?></h4>
    <div>
         <?php foreach($value as $innerkey=>$innerval): ?>
            <label class="label_check">
               <input name="line" value="<?php echo $i++; ?>" type="checkbox" />
               <?php echo $innernval; ?>
            </label>
        <?php endforeach; ?>
    </div>
<?php endforeach; ?>
