Question

我正在寻找一种方法来访问此JSON文件数据。我感兴趣的是提取名为documentjsonblob的属性，如下所示。

object(Quadrem\Model\Order)[201]
  protected '_dateCreated' => null
  protected '_buyerCode' => null
    array (size=2)
      2415 => 
        array (size=23)
          '@storeid' => string '813' (length=3)
          '@active' => string '1' (length=1)
          '@created' => string '2013-11-25 12:28:21' (length=19)
          'documentjsonblob' => string '{"HEAD":{"ORDERSEQUENCE":"0","TOTAL_TAX":7.9,"TOTAL_AMOUNT":86.9,"NUMBER":"AKMon3","TYPE":"NB","TYPE_NAME":"Standard PO","SUPPLIER":"0000002122","CREATED":"2013-04-29T12:00:00Z","CONTRACT_NUMBER":"","EXTERNAL_REFERENCE":"","CONTACT_PERSON":"Caroline Howlett","COMMENT":[""],"CURRENCY":"AUD","DELIVERY_TERMS":"DeliveryCondition|","PAYMENT_TERMS":[{"TEXT1":"21st day of next month after receipt"}],"NET_VALUE":79.0,"DELIVERY_ADDRESS":{"NAME_1":"KGTP FACILITY","NAME_2":"GAS TREATMENT PLANT","NAME_3":"KGPF","POSTAL_CODE":"6714","CITY":"Karratha","STREET":"Withnell Bay","REGION":"AUWA","REGION_NAME":"AUWA","COUNTRY":"AU"}]}' (length=3029)
          'documenttype' => string 'PO' (length=2)
      1890 => 
        array (size=23)
          '@storeid' => null
          '@active' => null

我不太确定哪种编码的JSON文件是这样的。如果有人可以提供帮助，我将不胜感激。

感谢。

由于您在评论中提到它是var_dump的输出而您想获得documentjsonblob，所以请按照以下步骤操作：

在第一行，您有object(Quadrem\Model\Order)[201]，这意味着您var_dumped 对象，比如$my_obj
第四行array (size=2)表示您有一个数组，您需要的是位于数组的第一个元素中，因此$my_obj[0]
$my_obj[0]包含一个关联数组，所需的索引为documentjsonblob，因此我们可以将 String 表示形式设为：

$my_arr = $my_obj[0]; $json_str = $my_arr['documentjsonblob'];

现在$json_str保存String表示，将其转换为PHP对象：

$json_obj = json_decode($json_str);

所以现在$json_obj拥有你想要的对象。
