PHP 获取和修改某些 RSS 标签的字符串

Question

我有一个游戏的 RSS 提要。仅从每个项目中提取然后修改和回显所选标签的文本的最佳方法是什么？

所以例如我想要的文本输出是：

Game: Rapunzel Split Up With Flynn (HTML5)
Category: girl
Image: http://www.website.com/thumb/201611/Rapunzel-Split-Up-With-Flynn.jpg
Game: Barbie Clean Place (HTML5)
Category: girl
Image: http://www.website.com/thumb/201611/Barbie-Clean-Place.jpg

还有更多项目，但我只展示了其中的 2 个。

有没有我可以使用的好的 RSS 或 XML 处理库或一些简单的代码？

Answer 1

获取您的 xml 并执行 json 或数组，以便您可以更轻松地访问它

$xml = '<xmlstuff></xmlstuff'; // Be warned of ' xml could cause error

$json = json_encode(simplexml_load_string($xml), true);
$arrays = json_decode($json, true);

echo "<pre>";
var_dump($arrays);
echo "</pre>";

现在您可以像访问数组一样访问数据了！

echo $name1 = $arrays['channel']['item'][0]['name']."<br>";
echo $name2 = $arrays['channel']['item'][1]['name']."<br><br>";

//MORE ADVANCED

foreach ($arrays['channel']['item'] as $items){
    echo $items['name']."<br>";
}

我在这里为您创建了一个页面，以便您查看它是如何转换和使用的！
