如何将json数据放入包含@属性的php变量中

Question

我一直在努力从apis中获取数组。不知道为什么我不能把我的头绕在他们头上。

这一次，我似乎无法访问密钥和结果。

我使用curl来获取json数组结果。然而，我似乎无法正确地访问它们。我一直收到php错误警告:非法字符串偏移量。显然我没有访问正确的密钥。

我试着用这种方式对它们进行解码、编码和访问，但没有结果。

我已经阅读了很多关于这里和其他地方的问题，只是无法让它起作用。

我的代码是：

<?php
$url="http://localhost/geeks/monitor/xml.php?plugin=complete&jsonp&callback=getData";
//  Initiate curl
$ch = curl_init();
// Disable SSL verification
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url);
// Execute
$resultjson=curl_exec($ch);
// Closing
curl_close($ch);

$array = json_decode(json_encode($resultjson), true);
print_r($array);
?>

它返回以下内容：

正如你所看到的，它不打印“友好”。所以，如果有人知道怎样才能让印刷品更容易读懂，那就太好了。然而，问题仍未解决。

因此，我如何访问其中的每一个，并将每个变量放入php变量。

我尝试了很多不同的方法，我显然没有正确选择钥匙。

Answer 1

哇哦！最后得到了它。从零开始并更改为file_get_contents。

然后，我抓起它，宣布utf8，并删除了它的垃圾。

然后，我确保我声明了json_decode为真，因此它将正确地放在一个数组中。

现在我可以很容易地获得我所需要的东西。下面是我的最后一段代码，列出了所有的数组，也是一个只访问我所需内容(版本)的示例：

<?php
$url="http://localhost/monitor/xml.php?plugin=complete&json&callback=getData";
$html = file_get_contents($url);
$json = preg_replace('/,\s*([\]}])/m', '$1', utf8_encode($html));

$json = json_decode($json, true);

echo '<p>Version : '.$json['Generation']['@attributes']['version'].'';

print_r($json);
?>

Answer 2

你可以这样读你的儿子：

$array['Generation']['@attributes']['version']

o/p => 3.2.x您可以在http://jsonlint.com/以适当的方式阅读您的json

Answer 3

json_decode($json，真)；

Array
(
    [Generation] => Array
        (
            [@attributes] => Array
                (
                    [version] => 3.2.x
                    [timestamp] => 1446194411
                )

        )

回波攻击

  echo $array["Generation"]["@attributes"]["timestamp"];
