我有来自api的回复。我希望在此密钥中显示[line_items]密钥的所有数据，所有食品都像食品名称，食品成本，客户订购的食品数量一样。我无法理解我错在哪里。
这是我的代码。
<?php
$url = 'http://localhost/cook-n-share/view-order/?cook_id='.$currnet_uid.''; //echo $url;
$content = file_get_contents($url);
$json = json_decode($content, true);
echo '<pre>';
print_r($json);
$i=1;
foreach( $json as $value){ ?>
<tr>
<td><?php echo $i; ?></td>
<td><?php echo $value['order']['billing_address']['first_name']; ?></td>
<td><?php echo $value['order']['line_items'][0]['name']; ?></td>
<td id="status"><?php echo $value['order']['status']; ?></td>
<?php } ?>
打印输出（$ json）
