  PHP SimpleXML + Get Attribute
  
  The XML I am reading looks like this:
  <show id="8511">
  
      <name>The Big Bang Theory</name>
      <link>http://www.tvrage.com/The_Big_Bang_Theory</link>
      <started>2007-09-24</started>
      <country>USA</country>
  
      <latestepisode>
          <number>05x23</number>
          <title>The Launch Acceleration</title>
      </latestepisode>
  
  </show>
  
  To get (for example) The number of the latest episode, I would do:
  $ep = $xml->latestepisode[0]->number;
  
  This works just fine. But what would I do to get the ID from <show id="8511"> ?
  I have tried something like:
  $id = $xml->show;
  $id = $xml->show[0];
  
  But none worked.
  Update
  My code snippet:
  $url    = "http://services.tvrage.com/feeds/episodeinfo.php?show=".$showName;
  $result = file_get_contents($url);
  $xml = new SimpleXMLElement($result);
  
  //still doesnt work
  $id = $xml->show->attributes()->id;
  
  $ep = $xml->latestepisode[0]->number;
  
  echo ($id);
  
  Ori. XML:
  http://services.tvrage.com/feeds/episodeinfo.php?show=The.Big.Bang.Theory
  
  A:
  
  This should work.
  $id = $xml["id"];
  
  Your XML root becomes the root of the SimpleXML object; your code is calling a chid root by the name of 'show', which doesn't exist.
  You can also use this link for some tutorials: http://php.net/manual/en/simplexml.examples-basic.php
  
  A:
  
  You need to use attributes
  I believe this should work
  $id = $xml->show->attributes()->id;
  
  A:
  
  This should work.
  You need to use attributes with type (if sting value use (string))
  $id = (string) $xml->show->attributes()->id;
  var_dump($id);
  
  Or this:
  $id = strip_tags($xml->show->attributes()->id);
  var_dump($id);
