PHP (XML到数组)获取作为数组的xml的属性

Question

你好，我得到了溢出游戏xml中的游戏。我设法将它转换为数组，但又出现了一个问题，问题是我想要得到的字符串位于数组内部，或者一个1节点的xml .I属性不能获得该属性。

我想要得到属性。

溢出游戏网站：http://publishers.spilgames.com/rss-3?limit=100&format=xml&category=Action

我到目前为止的代码是：

<?php

    $xml = simplexml_load_string(file_get_contents('http://publishers.spilgames.com/rss-3?limit=100&format=xml&category=Action')); /* Get the xml */
    $json = json_encode($xml);
    $games = json_decode($json); /* Make it an array */
    $game = $games->entries->entry;
    foreach($game as $entry) { /* Each game information */
        echo $entry->title;
        echo $entry->id;
        echo $entry->description;
        echo $entry->category;
        echo $entry->subcategory;
        echo $entry->technology;
        echo $entry->player->url;;
        echo $entry->thumbnails->small->url; /* Problems starts here */
   /* Because the thumbnails has 3 child but the info is inside of each child */
    }

?>

我在溢出游戏中得到的是xml而不是json，因为我不知道json是如何工作的。

如果我是您，我将学习JSON是如何工作的，因为它将使您的生活更轻松：

<?php
$json = file_get_contents('http://publishers.spilgames.com/rss-3?limit=100&format=json&category=Action');
$data = json_decode($json);

foreach ($data->entries as $entry) {
  echo $entry->title . "\n";
  echo $entry->id . "\n";
  echo $entry->description . "\n";
  echo $entry->category . "\n";
  echo $entry->subcategory . "\n";
  echo $entry->technology . "\n";

  echo $entry->thumbnails->small . "\n";
  echo $entry->thumbnails->medium . "\n";
  echo $entry->thumbnails->large . "\n";
}
?>
