如何从json中删除第一个数组名称

Question

我以JSON格式获取这样的值 -

   {
        "comments": [{
            "name": "ABC",
            "desc": "Hello...",
            "values": [{
                "status": "fine",
                "label": ""
            }]
        }, {
            "name": "XYZ",
            "desc": "Good Morning..",
            "values": [{
                "status": "fine",
                "label": "happy"
            }]
        }]
    }

但我不想要第一个数组名称意味着我需要这样的结果 -

[{
   "name": "ABC",
     "desc": "Hello...",
     "values": [{
         "status": "fine",
         "label": ""
      }]
  }, {
    "name": "XYZ",
    "desc": "Good Morning..",
     "values": [{
          "status": "fine",
          "label": "happy"
      }]
 }]

需要帮助...

Answer 1

这样做......

<?php
$json='{
        "comments": [{
            "name": "ABC",
            "desc": "Hello...",
            "values": [{
                "status": "fine",
                "label": ""
            }]
        }, {
            "name": "XYZ",
            "desc": "Good Morning..",
            "values": [{
                "status": "fine",
                "label": "happy"
            }]
        }]
    }';

    $arr=json_decode($json,1);
    echo json_encode($arr['comments']);

输出：

[{"name":"ABC","desc":"Hello...","values":[{"status":"fine","label":""}]},{"name":"XYZ","desc":"Good Morning..","values":[{"status":"fine","label":"happy"}]}]

试试这个：

---

$data = '[{
   "name": "ABC",
     "desc": "Hello...",
     "values": [{
         "status": "fine",
         "label": ""
      }]
  }, {
    "name": "XYZ",
    "desc": "Good Morning..",
     "values": [{
          "status": "fine",
          "label": "happy"
      }]
 }]';
$return = json_decode($data, true);
foreach ($return as $key => $value){        
    unset($return[$key]['name']);
}
echo '<pre>';
print_r($return);
echo '</pre>';
