Stripping down FQL JSON - php

Question

I'm using FQL to run this query
"SELECT post_id, actor_id, description, created_time, message, type, attachment FROM stream WHERE source_id = $page_id AND type > 0 LIMIT 0,9"
Which returns 10 items with a lot of information that isn't used and wanted some help and guidelines to help strip it down to something like
{
"image" : '...',
"text" : '...',
"username" : '...',
"userurl" : '...',
"userpic" : '...'
}
Can someone give me some tips on reformatting a JSON object?
Thanks

Answer 1

It works for me in a way like this:
https://graph.facebook.com/fql?q=SELECT%20aid%2C%20owner%2C%20name%2C%20object_id%20FROM%20album%20WHERE%20aid%3D%2220531316728_324257%22

Answer 2

Figured it out for myself, created a simple PHP class to hold the variables needed which are then added to an array.
For anyone interested here's the main bit of the code.
Class:
class Item{
public $image;
public $link;
public $text;
public $username;
public $userurl;
public $userpic;
}
Being used:
$feed = json_decode($feed);
$data = array();
foreach ($feed->data as $post){
$item = new Item;
if ($post->attachment->media){
if (isset($post->attachment->media[0]->src)){
$item->image = $post->attachment->media[0]->src;
}else if (isset($post->attachment->media[0]->photo->images[1]->src)){
$item->image = $post->attachment->media[0]->photo->images[1]->src;
}else if (isset($post->attachment->media[0]->src)){
$item->image = $post->attachment->media[0]->src;
}
$item->link = $post->attachment->media[0]->href;
}
$reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
$text = $post->message;
if(preg_match($reg_exUrl, $text, $url)){
$text = preg_replace($reg_exUrl, "".$url[0]." ", $text);
}
$item->text = $text;
$puser = number_format($post->actor_id,0,'','');
$url = "https://graph.facebook.com/$puser?fields=picture,name,link&access_token=$at";
$puser = file_get_contents($url);
$puser = json_decode($puser);
$item->userpic = $puser->picture->data->url;
$item->username = $puser->name;
$item->userurl = $puser->link;
$item->platform = "facebook";
$data[] = $item;
}
$this->response($data, 200);
}
hope this helps anyone else in the same situation.
