title: get all <meta property > using php
body: <p>How do I extract the "content" values of a  from the view source</p>
  
  <p>I have used CURL to get the source of the page but after that I'm not able to identify the following:</p>
  
  <pre><code>&lt;meta property="og:title" content="Zoe&amp;#39;s big surprise"&gt;
  &lt;meta property="og:description" content=" "&gt;
  &lt;meta property="og:type" content="video"&gt;
  &lt;meta property="og:image" content="http://i1.ytimg.com/vi/PNyMlswZb-I/hqdefault.jpg"&gt;
  </code></pre>
  
  <p>basically I need to capture all the above parameters in an array and use them.
  I have tried the following after curl</p>
  
  <pre><code>    //parsing begins here:
      $doc = new DOMDocument();
      @$doc-&gt;loadHTML($data);
      $nodes = $doc-&gt;getElementsByTagName('title');
  
      //get and display what you need:
      $title = $nodes-&gt;item(0)-&gt;nodeValue;
  
      $metas = $doc-&gt;getElementsByTagName('meta'); --This line is not able to fetch any &lt;meta&gt; content&gt;
  </code></pre>
  
  <p>Thanks</p>
