Question

所以我从api xml调用返回：

在浏览器中：

string(1005) " 0 0 56000 steadfast shared semidedicated dedicated vps vps_solusvm london shared vps vps_solusvm australia sis_group shared vps_solusvm 0.017 s 0.010 s 8676395012 "

在Google Chrome Elements中：

<ampa>
<command></command>0
<error_code>0</error_code>
<ttl>56000</ttl>
<datacenters>
    <n0>
        <name>steadfast</name>

现在我尝试实现一个非常简单的调用：

echo $result->ampa->datacenters->n0->name;

并收到此错误：

Trying to get property of non-object

处理这个xml我做错了什么？

BTW我的后端代码如下所示：

function index() {
    $result = $this->rest->get('/?auth_username=the-green-panda&auth_password=MacBook1&section=datacenters&command=get_datacenters');

    var_dump($result);

    echo '<hr/>';

    echo $result->ampa->datacenters->n0->name;
}

Answer 1

这是因为XML缺少结束</ampa>标记。

不要包含ampa。跟你一起去

$xml = simplexml_load_string($xml);
echo $xml->datacenters->n0->name;
