如何解码JSON字符串

Question

大家好!我可以请你帮我解码这个JSON代码:

$json = '{"inbox":[{"from":"55512351","date":"29\/03\/2010","time":"21:24:10","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."},{"from":"55512351","date":"29\/03\/2010","time":"21:24:12","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."},{"from":"55512351","date":"29\/03\/2010","time":"21:24:13","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."},{"from":"55512351","date":"29\/03\/2010","time":"21:24:13","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."}]}';

我想组织以上结构:

注1:

文件夹:收件箱

从(来自):......

日期(日期):......

时间(时间):......

utcOffsetSeconds:...

受托人(地址):......

受托人(姓名):......

状态(deliveryStatus):...

文字(正文):...

笔记2:

先感谢您!

您可以使用该json_decode函数来解码您的JSON字符串:

$json = '{"inbox":[{"from":"55512351","date":"29\/03\/2010","time":"21:24:10","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."},{"from":"55512351","date":"29\/03\/2010","time":"21:24:12","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."},{"from":"55512351","date":"29\/03\/2010","time":"21:24:13","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."},{"from":"55512351","date":"29\/03\/2010","time":"21:24:13","utcOffsetSeconds":3600,"recipients":[{"address":"55512351","name":"55512351","deliveryStatus":"notRequested"}],"body":"This is message text."}]}';
$data = json_decode($json);
var_dump($data);

你会得到这样的东西:

object(stdClass)[1]
  public 'inbox' => 
    array
      0 => 
        object(stdClass)[2]
          public 'from' => string '55512351' (length=8)
          public 'date' => string '29/03/2010' (length=10)
          public 'time' => string '21:24:10' (length=8)
          public 'utcOffsetSeconds' => int 3600
          public 'recipients' => 
            array
              0 => 
                object(stdClass)[3]
                  public 'address' => string '55512351' (length=8)
                  public 'name' => string '55512351' (length=8)
                  public 'deliveryStatus' => string 'notRequested' (length=12)
          public 'body' => string 'This is message text.' (length=21)
      1 => 
        object(stdClass)[4]
          public 'from' => string '55512351' (length=8)
          public 'date' => string '29/03/2010' (length=10)
          public 'time' => string '21:24:12' (length=8)
          public 'utcOffsetSeconds' => int 3600
          public 'recipients' => 
            array
              0 => 
                object(stdClass)[5]
                  public 'address' => string '55512351' (length=8)
                  public 'name' => string '55512351' (length=8)
                  public 'deliveryStatus' => string 'notRequested' (length=12)
          public 'body' => string 'This is message text.' (length=21)
      ....
      ....

现在你知道了数据的结构,你可以迭代它; 例如,你可以使用这样的东西:

foreach ($data->inbox as $note) {
  echo '<p>';
  echo 'From : ' . htmlspecialchars($note->from) . '<br />';
  echo 'Date : ' . htmlspecialchars($note->date) . '<br />';
  echo 'Body : ' . htmlspecialchars($note->body) . '<br />';
  echo '</p>';
}

你会得到这种输出:

From : 55512351
Date : 29/03/2010
Body : This is message text.

From : 55512351
Date : 29/03/2010
Body : This is message text.
