Php 如何解码JSON字符串

大家好！我能请你帮我解码这个JSON代码吗

$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."}]}';

我想将上述结构组织为：

注1： 文件夹：收件箱

From（From）：

日期：

时间：

utcOffsetSeconds:

最近（地址）：

最近者（姓名）：

状态（deliveryStatus）：

正文：

注2：

提前感谢您

您可以使用该函数来解码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);

你会得到这样的结果：

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)
      ....
      ....

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>';
}

现在您知道了数据的结构，可以对其进行迭代；例如，您可以使用如下内容：

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)
      ....
      ....

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>';
}

收件人属性似乎是数组，请尝试以下操作：

$json='{“收件箱”：[{“发件人”：“55512351”，“日期”：“29\/03\/2010”，“时间”：“21:24:10”，“utcOffsetSeconds”：3600，“收件人”：[{“地址”：“55512351”，“姓名”：“55512351”，“交付状态”：“未请求”}]，“正文”：“这是邮件文本”。}，{“发件人”：“55512351”，“日期”：“29\/03\/2010”，“时间”：“21:24:12”，“utcOffsetSeconds”：3600，“收件人”：“收件人”：“地址”：“55512351”，“姓名”：“55512351”，“deliveryStatus”：“notRequested”}]，“body”：“This is message text.”，{“from”：“55512351”，“date”：“29\/03\/2010”，“time”：“21:24:13”，“utcOffsetSeconds”：3600，“recipients”：[{“address”：“55512351”，“deliveryStatus”：“notRequested”}]，“body”：“This is message text.”，}，{“from”：“55512351”，“date”：“29\/03\/2010”，“time”：“21:24:13”，”utcOffsetSeconds“：3600，“收件人”：[{“地址”：“55512351”，“姓名”：“55512351”，“传递状态”：“未请求”}]，“正文”：“这是邮件文本。”}]}”；
$data=json_decode（$json）；
打印（数据）；
foreach（$data->收件箱为$note）
{
回声“”；
echo“From:”.htmlspecialchars（$note->From）。“
”；
回显“日期：”.htmlspecialchars（$note->Date）。“
”；
echo“Time:”.htmlspecialchars（$note->Time）。“
”；
回显“Body:”.htmlspecialchars（$note->Body）。“
”；
foreach（$note->recipients as$recipient）
{
回显“收件人（地址）：.htmlspecialchars（$recipient->address）。”
；
echo“To（name）：”.htmlspecialchars（$recipient->name）。“
”；
回显“状态：”.htmlspecialchars（$recipient->deliveryStatus）。“
”；
}
}

Pascal MARTIN，谢谢你的快速反应！但是这个乘法数组中的问题是。我真的不能用所有这些数组来操作，也不能像上面我想做的那样做一个简单的结构。请，我问你，你能演示一下我应该如何操作所有这些数组吗？你能用我不知道的foreach（）来演示它吗还是什么？谢谢你！@ilnur777:如果你不知道

foreach

，请阅读文档：.

for

和

foreach

循环是处理数组时必不可少的工具。帕斯卡·马丁，你救了我的命和我的神经！！！非常感谢。现在我真的可以理解如何在JSON上操作数组了！@ilnur777:不要忘记将Pascal的答案标记为正确答案：-）如果总是有一个且只有一个收件人，类似于

$note->recipients[0]->name

的方法应该可以工作；如果有时有多个收件人，您可以使用

foreach

循环在

$note->recipients

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>";
}
