Question

我正在尝试用PHP解析一些xml，并且可以构建正确的url来获取数据，但我仍然坚持确定如何查看结构的过程，以便我可以避免这样的错误

Notice: Trying to get property of non-object in C:\wamp\www\sportchecker\soccer.php on line 39
Call Stack
#   Time    Memory  Function    Location
1   0.0020  252360  {main}( )   ..\sports.php:0

以下是一个示例网址http://api.pinnaclesports.com/v1/leagues?sportid=29，是否可以告诉我如何在php代码中浏览树？我使用API密钥进行的调用返回了大量数据。这是我的代码

$url = "http://api.pinnaclesports.com/v1/feed?sportid=$sport_id&leagueid=$league_id&clientid=$client_id&apikey=$api_key&oddsformat=$oddsformat";
    $json_string = file_get_contents($url);
    $parsed_json = json_decode($json_string);

    // output the xml data
    $wSports = $parsed_json->sports->sport->id;
     echo "Status :  ${wSports} ";

     // test if url is correct
     echo $url;

编辑：这是一个数据样本，我试图让团队和时间回来。

使用simplexml。

$sports = new SimpleXMLElement($parsedJson);
$sports->sport[0]->id
