Question

我一直在努力从apis中获取数组。不知道为什么我不能把它包裹起来。

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。但是我似乎无法正确访问它们。我一直得到php错误警告：非法字符串偏移。显然我没有访问正确的密钥。

我尝试解码和编码并以这种方式访问它们无济于事。

我已经在这里和其他地方阅读了大量的问题，但是无法让它发挥作用。

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);
?>

返回以下内容：

正如你所看到的，它并不打印“友好”。因此，如果有人知道使这种印刷品更具人性可读性的最佳方法，那也会很棒。但仍然不是问题。

那么我怎样才能访问它们并将每个变量放入php变量中。

我尝试了很多不同的方法，显然我没有正确选择密钥。

Answer 1

你可以这样读你的json：

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

o / p =＆gt; 3.2.x中 您可以在http://jsonlint.com/

以适当的方式阅读您的json

Answer 2

json_decode（$ json，true）;

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

        )

echo attr

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

Answer 3

喔！结束了它。从头开始并更改为file_get_contents。

然后我抓住它并宣布utf8并从中取出垃圾。

然后我确定我声明json_decode为true所以它将在数组中正确。

现在我可以轻松访问我需要的内容。下面是我的最终代码列表所有作为一个数组，也是一个只访问我需要的版本（版本）：

<?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);
?>

如何将json数据导入到其中包含@attribute的php变量
