php loop through associative arrays

Question

Editing this code here on Stackoverflow and I'm really near to get the result I need.

So I have this code posted down here:

$friends = $facebook->api('/me/friends');
if(!empty($friends['data'])){
$size = variable_get('facebook_graph_pic_size_nodes','square');
$protocol = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') ? 'https' : 'http';
    foreach($friends['data'] as $data){
        $fbid = $data['id'];
        $fbfriendlikes[$fbid]=$facebook->api('/'.$fbid.'/likes'); 
    }

The $fbfriendlikes outputs me an array like this one : http://penelope-ns.net/fb/fig.jpg

What do I need to do is save the names in a $return value, all names.

Can someone please help me with this? Thanks.

Could we get the output in text, rather than an image? I've got a script that formats it. — SomeKittens

To me, it's just neccessary to output the names.. if it's in text format it's okay! — Ferat Ducellari

This should work.

$dataArray = $fbfriendlikes[$data['id']]['data'];
$result = "";
foreach($dataArray as $item){
    $result .= " ".$item['name'];
}

so, if i do return result, it's suppose to give me the names?.. Thanks!

$result should be a numerically-indexed array that contains the names from $fbfriendlikes.

Is this what you want?

$friends = $facebook->api('/me/friends');
$result= array();
if(!empty($friends['data'])){
    $size = variable_get('facebook_graph_pic_size_nodes','square');
    $protocol = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') ? 'https' : 'http';

    foreach($friends['data'] as $key => $data){
        $fbid = $data['id'];
        $result[$key] = $data;
        $fbfriendlikes[$fbid] = $facebook->api('/'.$fbid.'/likes'); 
    }
}

Hi Joao, thanks for the answer, i just need to output friends likes, the names of the pages.. does you code do this?

João Gonçalves Over a year ago

Sorry i misinterpreted the 'name' concept. Thought it refered to friends' names. This will give you an array with the name of the likes, yes.

Can you please do me this last favor? I need to store all names in a variable $result, because the module retrurn the $result! Can you please insert this one?

João Gonçalves Over a year ago

I believe this is it. Test it, because the image for the array you provided is quite hard to read.

Thanks for the help, the logic seems to be pure :)
