PHP - Parsing JSON from FB Graph

[TSeed]

Hello everyone, I am new to parsing and properly referencing JSON objects or associative arrays in PHP with the Facebook Graph API.

Here is an example of JSON i will be working with:
https://graph.facebook.com/comments/...layer_embedded

$request_url ="https://graph.facebook.com/comments/?ids=" . $purl;
$requests = file_get_contents($request_url);
$fb_response = json_decode($requests);

How can I implement a foreach function to cycle through and echo the id's of each element in the data array?

Thanks in advance!

It's just a bunch of nested objects with an array thrown in there.

foreach ($fb_response as $key => $response) {
  foreach ($fb_response->$key as $data) {
    foreach ($data as $item) {
      echo 'ID: ' . $item->id . '<br />';
      echo 'From ID: ' . $item->from->id . '<br />';
      echo 'From Name: ' . $item->from->name . '<br />';
      echo 'Message: ' . $item->message . '<br />';
      echo 'Timestamp: ' . $item->created_time . '<br /><br />';
    }
  }
}
