How to access object properties with names like integers?

I tried to decode the json result from youtube data api by the following code:

 $url="http://gdata.youtube.com/feeds/api/videos/$id?v=2&alt=jsonc";
    echo "$url".'<BR>';
    $json = file_get_contents($url,0,null,null);
    $json_output = json_decode($json);
    $items=$json_output -> data;

    $content = "{$items->content->1}";
    echo $content.'<BR>';

Everything works fine but the last two lines. Could someone please help?

And Here is the json result:

 {"apiVersion":"2.1","data":{"id":"9jDg3Dh28rE","uploaded":"2012-10-04T03:45:49.000Z",
........
 "content":{"5":"http://www.youtube.com/v/9jDg3Dh28rE?version=3&f=videos&app=youtube_gdata",
 "1":"rtsp://v5.cache8.c.youtube.com/CiILENy73wIaGQmx8nY43OAw9hMYDSANFEgGUgZ2aWRlb3MM/0/0/0/video.3gp",
 "6":"rtsp://v5.cache4.c.youtube.com/CiILENy73wIaGQmx8nY43OAw9hMYESARFEgGUgZ2aWRlb3MM/0/0/0/video.3gp"},"duration":2403,......}}

You need to wrap the numeric property with {} to access it.

$content = $items->content->{1};

And you also don’t need to use double quotes like below:

$thumbnail = "{$items->thumbnail->sqDefault}";

This should just be

$thumbnail = $items->thumbnail->sqDefault;
