如何在php中从数组构建的表中插入分隔符？

阿贝尔博尼利亚

嗨，我有这个从数组构建的表，但我想在每个描述组下插入一行并添加数量，但我不知道该怎么做。

链接到img 该表是使用此代码使用 foreach 构建的。

<?php
foreach ($resulta as $res) {
?>
    <tr>
        <th><?php echo $res['des'] ?></th>
        <th><?php echo $res['name'] ?></th>
        <th><?php echo $res['slug'] ?></th>
        <th><?php echo $res['details'] ?></th>
        <th><?php echo $res['price'] ?></th>
    </tr><?php } ?>

方法之一：

使用临时变量，例如 $total 初始值 =0 ，然后将其递增 $res["price"]

然后如果 des 发生变化（或在 foreach 循环的末尾），则显示此变量并将其重置为 0

样本数据

<?php
$resulta[] = array("des"=>"samsung led tv", "name"=>'', "slug"=>'', $details=>'', "price"=>"8.99");
$resulta[] = array("des"=>"samsung led tv", "name"=>'', "slug"=>'', $details=>'', "price"=>"41.99");
$resulta[] = array("des"=>"samsung led tv", "name"=>'', "slug"=>'', $details=>'', "price"=>"144.99");
$resulta[] = array("des"=>"macbook pro", "name"=>'', "slug"=>'', $details=>'', "price"=>"2499.99");
$resulta[] = array("des"=>"macbook pro", "name"=>'', "slug"=>'', $details=>'', "price"=>"649.99");
$resulta[] = array("des"=>"macbook pro", "name"=>'', "slug"=>'', $details=>'', "price"=>"148.99");
$resulta[] = array("des"=>"dell vostro 3557", "name"=>'', "slug"=>'', $details=>'', "price"=>"1499.99");
?>

PHP 代码

<table border=1>
<?php
$initdesc="undefined"; $count=0; $total=0;
foreach ($resulta as $res) {

  if ($initdesc !=$res["des"]) {
       if ($count > 0) { ?>
<tr><td colspan=4 style="text-align:right;">Total<td><?php echo $total; ?>
<?php  }
    $total=0;
    $initdesc=$res["des"];
  } 
?>
    <tr>
        <td><?php echo $res['des'] ?></td>
        <td><?php echo $res['name'] ?></td>
        <td><?php echo $res['slug'] ?></td>
        <td><?php echo $res['details'] ?></td>
        <td><?php echo $res['price'] ?></td>
    </tr>

<?php 
$count++;
$total=$total+$res['price'];        
}  

if ($count!=0) { ?>
<tr><td colspan=4 style="text-align:right;">Total<td><?php echo $total; ?>
<?php } ?>

</table>
