When I try to parse using simplexml_load_string or SimpleXMLElement I am getting this result.

当我尝试使用simplexml_load_string或SimpleXMLElement进行解析时，我得到了这个结果。

[ads] => SimpleXMLElement Object ( [@attributes] => Array ( [numAds] => 6 )

[ads] => SimpleXMLElement对象（[@attributes] =>数组（[numAds] => 6）

        [ad] => Array
            (
                [0] => SimpleXMLElement Object
                    (
                        [@attributes] => Array
                            (
                                [ranking] => 1
                            )

                        [title] => Artist News on Facebook®
                        [description] => What's the most current music news? Sign up For Free to Find out!
                        [pixel_url] => http://cc.xdirectx.com/pixellink.php?qry=e8b6b726c
                        [url] => http://cc.xdirectx.com/clicklink.php?qry=067a9027
                    )
               )

The important thing missing is url visibleurl attribute which I need. I tried looking online and wasted complete day in fixing this, but no answer. Can someone rectify the mistake I am doing?

缺少的重要事项是我需要的url visibleurl属性。我尝试在线查看并浪费了整整一天来解决这个问题，但没有答案。有人可以纠正我正在做的错误吗？

PHP CODE:

PHP代码：

$result = getCurlJson($urlParse);
$output = simplexml_load_string($result) or die("Error: Cannot create object");
echo '<pre>';
print_r($output);
echo '</pre>';

function getCurlJson($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_URL, $url);
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

#1

The loading of the XML works fine, but print_r is not able to print everything from an XML object. See this repository for a solution if you want to dump the XML code: simplexml_debug

加载XML工作正常，但print_r无法从XML对象打印所有内容。如果要转储XML代码，请参阅此存储库以获取解决方案：simplexml_debug

You can access the attribute you want with

您可以访问所需的属性

echo $output->ads->ad[0]->url->attributes();

Which works perfectly fine.

哪个效果很好。
