RSS Feed 提取为 JSON 对象

Question

这是我的 PHP 文件，名为 testClient

  **public function getXML() {

        $xml = simplexml_load_file('https:/.............');
        $feed1 = '<h3>' . $xml->channel->title . '</h3>';
        foreach ($xml->channel->item as $item) {
            $feed1 .= '<h4><a href="' . $item->link . '">' . $item->title . "</a></h4>";
        }
        $xml = simplexml_load_file('https://rumble.com/rss.php?target=sprinklevideo');
        $feed2 = '<h3>' . $xml->channel->description . '</h3>';
        foreach ($xml->channel->item as $item) {
            $feed2 .= '<h4><a href="' . $item->link . '">' . $item->description . "</a></h4>";
        }


        $xml = simplexml_load_file('https://rumble.com/rss.php?target=sprinklevideo');
        $feed3 = '<h3>' . $xml->channel->link . '</h3>';
        foreach ($xml->channel->item as $item) {
            $feed3 .= '<h4><a href="' . $item->link . '">' . $item->link . "</a></h4>";
        } 
        return $feed1;
}**

这是我的控制器class，我想在其中查看结果

**

use VideoBundle\VideoProviderClient\testClient as testClient;
    class MainController extends Controller
    {

   public function MainAction() {
        $zoo = new testClient();
        $val = $zoo->getXML();

        //dump 
        echo "<pre>";
        var_dump($val);       
        echo "</pre>";
        die();
        return new Response("$val");
    }
    public function setVal($val) {
        $this->item = json_encode($val);
        return $this;
    }
    public function getVal() {
        if ($this->item) {
            return json_decode($val);
        }
        return null;
    }

如果我想从 title/description/link 之类的 RSS 提要中获取数据，我正在获取这些数据。但是我如何才能将所有这些数据作为 JSON 对象。因为在 rss 提要中，数据保存为一个项目。

这是来自 RSS 提要的示例 "item" 数据 ---

<item>
<title>Newlyweds stun guests with epic first dance</title>
<description>
your foot in time to the music!
</description>
<link>

您将 HTML 添加到第一步的数据中。你应该在最后这样做。最好的选择是使用 Twig 模板。

然后将 XML 解析为 JSON 非常简单：

$xml = simplexml_load_string($xmlstring);
$json = json_encode($xml);
