php file get contents not working while fetching fb page data - php

Question

I have the following code to get fb page list
$graph_url_pages = "https://graph.facebook.com/me/accounts?access_token=".$_SESSION['token'];
$pagedata=file_get_contents($graph_url_pages);
echo "DATA : <br>";
print_r($pagedata);
$pages=json_decode($pagedata,true);
var_dump($pages);
$dropdown = "";
for($i=0;$i<count($pages->data);$i++)
{
if($me=="iamindex"){
$dropdown .= "<option value='".$pages->data[$i]->access_token."-".$pages->data[$i]->id."'>".$pages->data[$i]->name."</option>";
}elseif($me=="iammulti"){
$dropdown .= "<input type='checkbox' name='page' id='status' value='".$pages->data[$i]->access_token."-".$pages->data[$i]->id."'>".$pages->data[$i]->name."<br>";
}else{$dropdown.="<option value=''>No Category Selection</option>";}
}
$pagedata and $pages is empty and so dropdown doesn't get populated.
Somewhere at the top of the page I am using Ob_start() and at the end Ob_flush(); And they are needed. I don't know whether this is the issue.
Would be great if somebody can point out what is going wrong ! if more code is needed, I can provide. Please note I am an amateur programmer. Self taught.

I recommend using cURL
$graph_url_pages = "https://graph.facebook.com/me/accounts?access_token=".$_SESSION['token'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $graph_url_pages);
if(curl_error($c))
{
echo 'error:' . curl_error($c);
//it will produce the error if any exists
}
$data = curl_exec($ch);
curl_close($ch);
print_r($data);
