title: Get the first entry of a JSON object
body: <p>Facebook gives a JSON stream like this:</p>
  
  <pre><code> "actions": [
      {
         "name": "Comment",
         "link": "http://www.facebook.com/100000335233539/posts/193845507303289"
      },
      {
         "name": "Like",
         "link": "http://www.facebook.com/100000335233539/posts/193845507303289"
      },
      {
         "name": "Read entire article",
         "link": "http://www.domain.tld/article/"
      }
   ],
  </code></pre>
  
  <p>I want to get the first of the three objects with:</p>
  
  <pre><code>$link = ($feeditem['actions']['link']);
  </code></pre>
  
  <p>But I always get only the last entry.
  How can I get the first one?</p>
