对 php 和 XML 来说还是很新的东西,一段时间以来一直试图找到解决方案。
我正在尝试比较两个 XML 返回并仅显示它们中存在的子项。具体来说,我正在使用 Steam api 从两个输入的 Steam id 中获取游戏库,我想显示两个用户都拥有的游戏。
它现在将显示用户 1 拥有的所有游戏,而不是这样做。
这是我遇到问题的部分,$apinyckel 是 API 密钥,我没有将它包含在这篇文章中,因为它不应该被共享。
$steamid2 = $_SESSION['steamid2'];
$steamid3 = $_SESSION['steamid3'];
//user1
$url4 = "http://api.steampowered.com/IPlayerService/GetOwnedGames/v0001/?key=$apinyckel&steamid=$steamid2&format=xml&&include_appinfo=1";
$data4 = file_get_contents($url4);
$xml4 = simplexml_load_string($data4);
//user2
$url5 = "http://api.steampowered.com/IPlayerService/GetOwnedGames/v0001/?key=$apinyckel&steamid=$steamid3&format=xml&&include_appinfo=1";
$data5 = file_get_contents($url5);
$xml5 = simplexml_load_string($data5);
foreach ($xml4->games->children() as $item2):
if ($xml4->games->child->appid === $xml5->games->child->appid) {
?><img src="http://media.steampowered.com/steamcommunity/public/images/apps/<?echo htmlentities($item2->appid);?>/<?echo htmlentities($item2->img_logo_url);?>.jpg"><?
}
endforeach;
下面是其中一位用户的 XML 结构的示例。
