Facebook Stream.Get -- How to access data in array?

On stream.get, I try to

echo $feeds["posts"][$i]["attachment"]["href"];

It return the URL, but, in the same array scope where "type" is located (which returns string: video, etc), trying $feeds["posts"][$i]["attachment"]["type"] returns nothing at all!

Here's an array through PHP's var_dump: http://pastie.org/930475

So, from testing I suppose this is protected by Facebook? Does that makes sense at all?

Here it's full: http://pastie.org/930490, but not all attachment/media/types has values.

It's also strange, because I can't access through [attachment][media][href] or [attachment][media][type], and if I try [attachment][media][0][type] or href, it gives me a string offset error.

["attachment"]=> array(8) {
    ["media"]=> array(1) {
        [0]=> array(5) {
            ["href"]=> string(55) "http://www.facebook.com/video/video.php?v=1392999461587"
            ["alt"]=> string(13) "IN THE STUDIO"
            ["type"]=> string(5) "video"

My question is, is this protected by Facebook? Or we can actually access this array position?

Well, once the data is returned to you, it can no longer be protected by Facebook. You have full access to everything in that result as a regular data structure.

From the looks of it, there are multiple href properties throughout, so you'll want to be careful which one you're going for. $feeds["posts"][$i]["attachment"]["href"] is a valid element for some items, but $feeds["posts"][$i]["attachment"]["media"][0]["href"] is also a valid element.

There doesn't appear to be a $feeds["posts"][$i]["attachment"]["type"] element though, so that's why you're getting nothing for that particular item. There is a type inside ["attachment"]["media"][0] however, which is probably what you want.

If you are getting a string offset error when using array syntax, you've probably mixed up an element somewhere. Strings can be accessed via array syntax. For example:

$str = "string";
echo $str[1];  //echos 't'

You would get an offset warning if you tried to access an index that was larger than the string. In any case, from the looks of that output, $feeds["posts"][$i]["attachment"]["media"][0]["type"] should work.
