從Plex Media Server獲取XML數據

Question

我想從Plex Media Server槽中獲取信息foreach。我成功地從URL中獲取內容，但無法獲取我想要在頁面上打印的信息。

這是從URL中的var_dump：

object(SimpleXMLElement)[1] 
    public '@attributes' => 
    array 
     'size' => string '349' (length=3) 
     'mediaTagPrefix' => string '/system/bundle/media/flags/' (length=27) 
     'mediaTagVersion' => string '1322272914' (length=10) 
     'sortAsc' => string '1' (length=1) 
     'viewGroup' => string 'movie' (length=5) 
     'viewMode' => string '458803' (length=6) 
     'art' => string '/:/resources/movie-fanart.jpg' (length=29) 
     'title1' => string 'Filmer' (length=6) 
     'identifier' => string 'com.plexapp.plugins.library' (length=27) 
    public 'Video' => 
    array 
     0 => 
     object(SimpleXMLElement)[2] 
      public '@attributes' => 
      array 
       ... 
      public 'Media' => 
      object(SimpleXMLElement)[351] 
       ... 
      public 'Genre' => 
      array 
       ... 
      public 'Writer' => 
      array 
       ... 
      public 'Director' => 
      object(SimpleXMLElement)[356] 
       ... 
      public 'Country' => 
      object(SimpleXMLElement)[357] 
       ... 
      public 'Role' => 
      array 
       ... 
    1 => 
    object(SimpleXMLElement)[3] 
     public '@attributes' => 
     array 
      ... 
     public 'Media' => 

And so on... 

這是從URL中的print_r數據：

När Cameron börjar high school förälskar han sig snabbt i den söta Bianca. Han hjälper henne med hemläxorna i franska för att få henne att bli intresserad av honom. När han ber att få gå på skolbalen med henne får han dock veta att hennes pappa har bestämt att hon inte får gå på dejt så länge Biancas syster Kat är singel. Kat är ständigt på dåligt humör och ovänlig och definitivt inte någon man vill gå på dejt med. Cameron måste också konkurrera om Biancas gunst med snyggingen Joey. Cameron kommer då på en plan: att be Pat, som enligt ryktet har sålt sin lever för att köpa högtalare, att gå med Kat på skolbalen mot betalning.

這是代碼，我現在所擁有的：

$url = 'http://localhost:32400/library/sections/12/all'; 
$achxml = simplexml_load_file($url); 
foreach($achxml->attributes AS $ach) { 
    echo $ach->Video['title'].'<br>'; 
} 

我從中得到的唯一東西是......好 - 沒有！它不打印任何東西！所以我現在問你，我的foreach有什麼問題？你可以閱讀更多關於PlexNine或他們現在稱之爲的東西，在這裏：http://wiki.plexapp.com/index.php/PlexNine_AdvancedInfo

在此先感謝。

我現在得到這個工作！以下是解決方案：

foreach($achxml->Video AS $child) { 
    echo $child['title']; 
}
