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

From（from）：...

日期（日期）：...

时间（时间）：......

utcOffsetSeconds：...

接收人（地址）：......

接收人（姓名）：......

状态（deliveryStatus）：...

文字（正文）：...

注2：

提前谢谢！

Answer 1

您可以使用json_decode函数解码您的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.

Answer 2

看起来recipients属性是一个数组，试试这个：

$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);
print_r($data);

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

        foreach($note->recipients as $recipient)
        {
            echo 'To (address) : ' . htmlspecialchars($recipient->address) . '<br />';
            echo 'To (name)    : ' . htmlspecialchars($recipient->name) . '<br />';
            echo 'Status       : ' . htmlspecialchars($recipient->deliveryStatus) . '<br />';
        }
    }

Answer 3

enter code here
<?php
$subject = file_get_contents('http://example.com/subject.php');
$subject_arr = json_decode($subject);

$my = $subject_arr->info;

for($i=0;$i<=1000;$i++){
echo $my[$i]->subject_name;
echo "<br>";
}
echo $my[0]->subject_name;

?>
<?php
$subject = file_get_contents('http://example.com/subject.php');
$subject_arr = json_decode($subject);

$my = $subject_arr->info;

for($i=0;$i<=1000;$i++){
echo $my[$i]->subject_name;
echo "<br>";
}
?>
