【问题描述】：

"**6732987ae9ac9ac3d465ea993bf9425c**": "rowId":"6732987ae9ac9ac3d465ea993bf9425c","id":14,"name":"Stanley Metz","qty":2,"price":2039,"weight":550,"options":"size":"large","discount":0,"tax":428.19,"subtotal":4078,"49b94e7c1fec3ef5540a81145e603955":"rowId":"49b94e7c1fec3ef5540a81145e603955","id":3,"name":"Ms. Emmie Macejkovic","qty":1,"price":4478,"weight":550,"options":"size":"large","discount":0,"tax":940.38,"subtotal":4478

我们可以看到这是订单数据库中订单中的一行的一列，所以我需要访问键 6732987ae9ac9ac3d465ea993bf9425c 的嵌套对象，以便在管理员中显示订单面板刀片

【参考方案1】：

如果你总是只有一把钥匙，那么你可以简单地使用；

$data = json_decode($jsonComesHere , true);
$data = array_values($data)[0];
print_r($data['name']); //or whatever you need

如果你有多个对象键

$datas = json_decode($jsonComesHere , true);
$datas = array_values($datas);
foreach($datas as $data)
 print_r($data['name']); //or whatever you need
