在php中用多个对象解码json数组

我无法解码包含多个对象的JSON数组。任何形式的帮助都将被充分利用

    {  
   "article_details":[  
      {  
         "article_code ":"000000000300028156 ",
         "diff_amnt ":"1 "
      },
      {  
         "article_code ":"000000000300028174 ",
         "diff_amnt ":"1 "
      },
      {  
         "article_code ":"000000000300028126 ",
         "diff_amnt ":"1 "
      }
   ],
   "article":[  
      {  
         "article_code ":"000000000300028156 ",
         "diff_amnt ":"1 "
      },
      {  
         "article_code ":"000000000300028174 ",
         "diff_amnt ":"1 "
      },
      {  
         "article_code ":"000000000300028126 ",
         "diff_amnt ":"1 "
      }
   ]
}

使用PHP函数

使用PHP函数

json\u decode

的结果是一个具有两个属性的对象，

article\u details

和

article

它们中的每一个都是一个对象数组

但是内部对象属性有一个尾随空格，

“article\u code”

和

“diff\u amnt”

您可以按如下方式对它们进行迭代

$object = json_decode($str);

foreach($object->article_details as $articleDetails){

    print $articleDetails->{"article_code "} . PHP_EOL;
}


foreach($object->article_details as $article){
    print $article->{"diff_amnt "} . PHP_EOL;
}

还要注意，这些值后面有一个空格。
要么修复它的来源，要么像这样过滤

json

字符串中的尾随空格

$jsonString = str_replace(' "','"',$jsonString);

显式删除双引号前的任何尾随空格。
然后以通常的方式访问对象属性

foreach($object->article_details as $articleDetails){
    print $articleDetails->article_code . PHP_EOL;
}


foreach($object->article_details as $article){
    print $article->diff_amnt . PHP_EOL;
}

}

尝试一下：

$json = '
{
   "article_details":[  
      {  
         "article_code ":"000000000300028156 ",
         "diff_amnt ":"1 "
      },
      {  
         "article_code ":"000000000300028174 ",
         "diff_amnt ":"1 "
      },
      {  
         "article_code ":"000000000300028126 ",
         "diff_amnt ":"1 "
      }
   ],
   "article":[  
      {  
         "article_code ":"000000000300028156 ",
         "diff_amnt ":"1 "
      },
      {  
         "article_code ":"000000000300028174 ",
         "diff_amnt ":"1 "
      },
      {  
         "article_code ":"000000000300028126 ",
         "diff_amnt ":"1 "
      }
   ]
}';

$key = 'article_code '; // Since your key is 'article_code ' but not 'article_code', I have to do this
$dataObject = json_decode($json);
echo $dataObject->article_details[0]->$key; // This will out put: 000000000300028156 
$dataArray = json_decode($json, true);
echo $dataArray['article_details'][0]['article_code ']; // This will out put: 000000000300028156 

尝试一下：

$json = '
{
   "article_details":[  
      {  
         "article_code ":"000000000300028156 ",
         "diff_amnt ":"1 "
      },
      {  
         "article_code ":"000000000300028174 ",
         "diff_amnt ":"1 "
      },
      {  
         "article_code ":"000000000300028126 ",
         "diff_amnt ":"1 "
      }
   ],
   "article":[  
      {  
         "article_code ":"000000000300028156 ",
         "diff_amnt ":"1 "
      },
      {  
         "article_code ":"000000000300028174 ",
         "diff_amnt ":"1 "
      },
      {  
         "article_code ":"000000000300028126 ",
         "diff_amnt ":"1 "
      }
   ]
}';

$key = 'article_code '; // Since your key is 'article_code ' but not 'article_code', I have to do this
$dataObject = json_decode($json);
echo $dataObject->article_details[0]->$key; // This will out put: 000000000300028156 
$dataArray = json_decode($json, true);
echo $dataArray['article_details'][0]['article_code ']; // This will out put: 000000000300028156 

用于解码JSON字符串，如下所示：

$json_array = json_decode($json, true);
                                  ^ When TRUE, returned objects will be converted into associative arrays.

// Here $json is your json string
$json_array = json_decode($json, true);

foreach($json_array as $key => $arrays){
    echo $key . "<br />";
    foreach($arrays as $array){
        foreach($array as $key => $value){
            echo $key . " => " . $value . "<br />";
        }
    }
    echo "<br />";
}

因此，您的代码应该如下所示：

$json_array = json_decode($json, true);
                                  ^ When TRUE, returned objects will be converted into associative arrays.

// Here $json is your json string
$json_array = json_decode($json, true);

foreach($json_array as $key => $arrays){
    echo $key . "<br />";
    foreach($arrays as $array){
        foreach($array as $key => $value){
            echo $key . " => " . $value . "<br />";
        }
    }
    echo "<br />";
}

// Here $json is your json string

    }
    echo "<br />";
}

        }
    }
    echo "<br />";
}
