Reading JSON in this scenario?

Question

I am trying to parse rss feeds from various sources,one of such source is this:http://feeds.feedburner.com/DiscoveryNews-Top-Stories

But this source is giving me some weird json data like this:

"item": [
    {
     "title": [
      "Snazzy Science Photos of the Week (August 10-16)",
      {
       "type": "html",
       "content": "Snazzy Science Photos of the Week (August 10-16)"
      }
     ],
     "description": [
      "Glowing rabbits, treasure-hunting badgers and a case of mistaken UFO identity help round out this week&#039;s photos.<img src=\"http://feeds.feedburner.com/~r/DiscoveryNews-Top-Stories/~4/S6Urfvdw2DQ\" height=\"1\" width=\"1\"/>",
      {
       "type": "html",
       "content": "Glowing rabbits, treasure-hunting badgers and a case of mistaken UFO identity help round out this week&#039;s photos."
      }
     ],

Currently,I'm using the following code to get titles of the posts:

if(isset($jit->title->content)){
                $title = $decoded_json->query->results->item->title->content;
            }else{
                $title = $decoded_json->query->results->item->title;
            }

But the above code fails when I try to parse Discovery news feed.Please help?

[EDIT]: I'm using YQL to get the equivalent JSON from the source.This is the link

Answer 1

It is packing up the elements as an array:

"title": [
          "No Battery Required for This Wireless Device",
          {
              "type": "html",
              "content": "No Battery Required for This Wireless Device"
          }
         ],

You can read the first element like this:

<?php
$url = 'http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20feed%20where%20url=%22http://feeds.feedburner.com/DiscoveryNews-Top-Stories%22&format=json&diagnostics=true&callback=cbfunc';
$data = substr(file_get_contents($url), 7, -2);
$json = json_decode($data);
foreach ($json->query->results->item as $item)
{
    echo "Title: ", $item->title[0], "\nDescription: ", $item->description[0], "\n";
    echo "==================================================\n\n";
}

Or using SimpleXML library:

$url = 'http://feeds.feedburner.com/DiscoveryNews-Top-Stories?format=xml';
$xml = simplexml_load_string(file_get_contents($url));
foreach ($xml->channel->item as $item)
{
    echo "Title: ", $item->title, "\nDescription: ", $item->description, "\n";
    echo "==================================================\n\n";
}
