title: Loop through json array of objects issue
body: <p>Hi I'm trying to loop through a json array of objects but I literally get nothing back, here is my attempt.</p>
  
  <pre><code> $jsonurl = 'http://eol.org/api/search/1.0.json?q='."$searchvar".'&amp;page=1&amp;exact=false&amp;      filter_by_taxon_concept_id=&amp;filter_by_hierarchy_entry_id=&amp;filter_by_string=&amp;cache_ttl=';
   $json = file_get_contents($jsonurl,0,null,null);
   $json_output = json_decode($json);
  
  foreach ($json_output-&gt;dataObjects as $objects){
      print "{$objects-&gt;title}\n";
  }
  </code></pre>
  
  <p>here is the structure of the actual json array.</p>
  
  <pre><code>array
  
  0    object
       id     19076
       title  Vulpes
       link   http://eol.org/19076?action=overview&amp;controller=taxa
       content    Arctic foxes; kit foxes; red foxes; red fox
  </code></pre>
