Issue Fixed with cURL request:
<?php namespace AdClass;
use stdClass;
class AdInfo{
private $domain;

private $sponsored_count;

private $internal_count;
public function __construct($domain,$widget_id,$sponsored_count=1,$internal_offset=1, $sponsored_offset=0,$internal_count=3)
{
$this->domain = $domain;
$this->widget_id = $widget_id;
$this->api_key = "XXXX";
$this->pub_id = xxxx;
$this->sponsored_offset =$sponsored_offset;
$this->sponsored_count = $sponsored_count;
$this->internal_offset = $internal_offset;
$this->internal_count = $internal_count;
}
public function getAdContent()
{
$curl = curl_init();
// Set some options - we are passing in a useragent too here
curl_setopt_array($curl, array(

// Send the request & save response to $resp

curl_close($curl);
return $resp;
