Youtube API PHP json decode - php

Question

I'm trying to search youtube and grab the videos video ID and title.
In the bellow example I am searching for "youtube":
<?php
$url="http://gdata.youtube.com/feeds/api/videos?q='youtube'&format=5&max-results=2&v=2&alt=jsonc";
$json = file_get_contents($url,0,null,null);
$json_output = json_decode($json);
echo '<pre>';
print_r("query results:");
print_r($json_output);
'</pre>';
foreach ( $json_output->data as $data ){
echo "{$data->id}";
echo "{$data->title}";
}
?>
Here is the json output for the above query:

Im trying to echo out [id] and [title]. Any idea what I am doing wrong?
Thanks!

Answer 1

Change line 9 to:
foreach ( $json_output->data->items as $data ){

Answer 2

You should get first items as an Objects Array:
$items = $json -> data -> items;
So try foreach now:
foreach ( $items as $item ){
echo "{$item->id}";
echo "{$item->title}";
}
I hope it's clear now.
