title: parse PHP array
body: <p>I have managed to get to the stage where I have an array that looks like this. Used (zend_json to decode a json response)</p>
  
  <pre><code>Array
  (
  [response] =&gt; Array
      (
          [status] =&gt; ok
          [userTier] =&gt; free
          [total] =&gt; 10
          [startIndex] =&gt; 1
          [pageSize] =&gt; 10
          [currentPage] =&gt; 1
          [pages] =&gt; 1
          [results] =&gt; Array
              (
                  [0] =&gt; Array
                      (
                          [id] =&gt; lifeandstyle/series/cycling
                          [type] =&gt; series
                          [webTitle] =&gt; Cycling
                          [webUrl] =&gt; http://www.guardian.co.uk/lifeandstyle/series/cycling
                          [apiUrl] =&gt; http://content.guardianapis.com/lifeandstyle/series/cycling
                          [sectionId] =&gt; lifeandstyle
                          [sectionName] =&gt; Life and style
                      )
  
                  [1] =&gt; Array
                      (
                          [id] =&gt; sport/cycling
                          [type] =&gt; keyword
                          [webTitle] =&gt; Cycling
                          [webUrl] =&gt; http://www.guardian.co.uk/sport/cycling
                          [apiUrl] =&gt; http://content.guardianapis.com/sport/cycling
                          [sectionId] =&gt; sport
                          [sectionName] =&gt; Sport
                      )
  </code></pre>
  
  <p>How would I go about parsing only the elements that are [webTitle] and [webUrl]</p>
  
  <p>Thanks!</p>
