因此,我已閱讀了幾篇有關使用simpleXML讀取XML的主題,但我遇到了與特定案例有關的問題。使用simplexml和PHP讀取Steam Web API
目前,我試圖從該來自於蒸汽網絡API URL
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE response>
<response>

這個XML塊單值,我可以輸出所有的這一個網頁用下面的PHP代碼(代碼有來自另一篇文章,這是難以置信的幫助
$url = "http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=[STEAMAPIKEY]&steamids=[PROFILEID]&format=xml";
$get = file_get_contents($url);
$xml = simplexml_load_string($get);
header('Content-Type: text/xml');
die($xml->asXML());
然而,當我試圖改變$ XML-> asXML()像文檔其他元素來說,像這樣:
echo '<p>'.$xml->response->players->player->personastate.'</p>;
我收到一條錯誤消息,說沒有返回數據。
出於示例的目的,我試圖檢索指示玩家是否在線的元素<personastate>
。
