Facebook feeds on website - php

Question

I'm trying to get some fb feeds on a website. I've searched the web and found a couple things I could try. After failing quite a bit, I've managed to get it. Today the access token wasn't valid anymore, so I got a new one and it worked again. After a bit (token still valid) it didn't anymore (got two messages). So I searched again and found a new solution that works and I think that gives me a token which is longer valid. This is the php code:
<?php
$limit = 3;
$profile_id = "32796xxxxx64243";
//App Info, needed for Auth
$app_id = "59351xxxxx41974";
$app_secret = "082d36fe4108ae51xxxxxxxxxxfb84b4";
//retrieve a new Auth token
$curl = 'https://graph.facebook.com/oauth/access_token?grant_type=client_credentials&client_id='.$app_id.'&client_secret='.$app_secret;
//$authToken = file_get_contents($curl);
$authToken = file_get_contents("https://graph.facebook.com/oauth/access_token?type=client_cred&client_id={$app_id}&client_secret={$app_secret}");
$data = file_get_contents("https://graph.facebook.com/{$profile_id}/feed?{$authToken}");
echo $data;
?>
This gives me following result:
Now I'm trying to get all the info out of it, but here is where I'm getting an error in my foreach loop. This is the code I use:
<div id="footer">
<h5>Laatste Facebook feeds</h5>
<div class="wrapperfb">
<?
$counter = 0;
foreach($data->data as $d){
if($counter==$limit)
break;
?>
<div class="singlefb">
<div class="imgfb">
<a class="afb" href="http://facebook.com/profile.php?id=<?=$d->from->id?>">
<img border="0" alt="<?=$d->from->name?>" src="https://graph.facebook.com/<?=$d->from->id?>/picture"/>
</a>
</div>
<div class="textfb">
<span style="font-weight:bold"><a class="afb" href="http://facebook.com/profile.php?id=<?=$d->from->id?>">
<?=$d->from->name?></a></span><br/>
<span style="color: #999999;">on <?=date('F j, Y H:i',strtotime($d->created_time))?></span>
<br/>
<?=$d->message?>
</div>
</div>
<?
$counter++;
}
?>
</div>
</div>
This is the error I'm getting:
Warning: Invalid argument supplied for foreach() in
/customers/9/2/3/beach-korfbal.be/httpd.www/facebookFeeds.php on line
19
line 19 is the foreach loop:
foreach($data->data as $d){
It's probably something stupid I'm looking over. Could someone please help me out. This is the last thing I need to complete to launch the site.

It works now thanks to Abhik Chakraborty's comment.
This is the full code:
<?php
$limit = 5;
$profile_id = "32796xxxxx64243";
//App Info, needed for Auth
$app_id = "59351xxxxx41974";
$app_secret = "082d36fe4108ae51xxxxxxxxxxfb84b4";
//retrieve a new Auth token
$authToken = file_get_contents("https://graph.facebook.com/oauth/access_token?type=client_cred&client_id={$app_id}&client_secret={$app_secret}");
$data = json_decode(file_get_contents("https://graph.facebook.com/{$profile_id}/feed?{$authToken}"));
?>
<div id="footer">
<h5>Laatste Facebook feeds</h5>
<div class="wrapperfb">
<?
$counter = 0;
foreach($data->data as $d){
if($counter==$limit)
break;
?>
<div class="singlefb">
<div class="imgfb">
<a class="afb" href="http://facebook.com/profile.php?id=<?=$d->from->id?>">
