我是PHP和JSON的新手，但遇到问题，我想从JSON检索项目和值：

      },
      "custom_fields": [
        {
          "name": "user_id",
          "value": 184191

      ],
      "user_agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_3)"
    }
  }
}

我想从数据->订单中检索项目，例如“ id”或“ ip_address”。谢谢您的阅读，我希望有人能对此有所帮助，因为我迷路了，我最近才开始编写代码，我正努力学习很多东西。

致谢！

Answer 1

您可以从JSON数据中提取需要的数组。您也可以使用循环来读取订单数组中的所有数据。

$array = json_decode($json, true);

$verbose = $array['data'];
$orderArray = $verbose['order'];

print_r($orderArray);

echo $orderArray['id'];
echo $orderArray['ip_address'];

Answer 2

test.json是您上载的json，将其放置在名为test.json的文件中，并确保将其放置在同一目录中。

<?php

$load = file_get_contents("test.json") or die("JSON load failed");    
$json_a = json_decode($load, true);
print $json_a['data']['order']['ip_address'] . "\n"; 

?>

我的回答是从文件中读取JSON，就像直接将其转储到您的代码中一样（确实如此），这会使代码的可读性降低，文件也变得更加混乱。

如果您不想将文件放在同一目录中，只需指定完整的文件路径。例如。 file_get_contents("this/dir/here/test.json");

您可以了解here的工作原理，json_decode的工作原理非常重要，我们需要向其传递true参数以构成arrays associative。
