PHP decode nested JSON

[Pr0haXer]

I've a nested JSON code as (it's actually my facebook status updates)\[code\]{ "data": [ { "id": "1290561400000000", "from": { "name": "My name", "id": "500920000" }, "message": "Message body", "updated_time": "2010-08-24T08:22:13+0000", "comments": { "data": [ { "id": "129056140474641_8000", "from": { "name": "name1", "id": "100000486072000" }, "message": "hahahahahahha..........", "created_time": "2010-08-24T08:40:39+0000" }, { "id": "129056140474641_8000000", "from": { "name": "name2", "id": "1597542457" }, "message": "true ya. I have updated", "created_time": "2010-08-24T08:59:53+0000" }, { "id": "129056140474641_83000", "from": { "name": "Name3", "id": "1000004860700000" }, "message": "am putting it on my wall....", "created_time": "2010-08-24T09:01:25+0000" } ], } }]\[/code\]Now how do I access the comments for a particular update and print it through a loop?? (I'm retrieving say a couple of updates at the same time).
