Question

<?php
function fetchUrl($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 20);
$feedData = curl_exec($ch);
curl_close($ch);
return $feedData;
}
$profile_id = "xxxxxxxxxxxxx";
//App Info, needed for Auth
$app_id = "xxxxxxxxxxxx";
$app_secret = "xxxxxxxxxxx";
$authToken = fetchUrl("https://graph.facebook.com/oauth/access_token?type=client_cred&client_id={$app_id}&client_secret={$app_secret}");
$json_object = fetchUrl("https://graph.facebook.com/{$profile_id}/posts?{$authToken}");
$feedarray = json_decode($json_object);
echo $json_object;
foreach ( $feedarray->data as $feed_data )
{
echo "<h2>{$feed_data->name}</h2><br />";
echo "{$feed_data->message}<br /><br />";
}
?>
When I try to run my code with my details (fully open page), I get an output of
Warning: Invalid argument supplied for foreach() in /home/xxxxxxxxx/public_html/includes/footer.php on line 52
When I use the code below it prints bool(false).
$feedData = curl_exec($ch);
var_dump($feedData); die();
I have worked out that the fetchUrl's are not working and I have tried many different others but none seem to work...
Any ideas?
