How to echo cURL Response from REST php - php

Question

I newbie on PHP, REST and cURL. I'm try to build an application to do GET and POST request. I did some tutorials and read cURL documentations.
I did GET request and get some response but I could not get my actual need :)
Here is my code.
<?php
$url = 'https://ise.cisco.connect:9060/ers/config/portal';
$method = 'GET';
// headers and data (this is API dependent, some uses XML)
$headers = array(
'Accept: application/vnd.com.cisco.ise.identity.portal.2.0+xml'
);
$data = json_encode(array(
'firstName'=> 'John',
'lastName'=> 'Doe'
));
$username = 'sponsor';
$password = 'Password1';
$handle = curl_init();
curl_setopt($handle, CURLOPT_URL, $url);
curl_setopt($handle, CURLOPT_USERPWD, $username.':'.$password);
curl_setopt($handle, CURLOPT_HEADER, 1);
curl_setopt($handle, CURLOPT_HTTPHEADER, $headers);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($handle, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, false);
switch($method)
{
case 'GET':
break;
case 'POST':
curl_setopt($handle, CURLOPT_POST, true);
curl_setopt($handle, CURLOPT_POSTFIELDS, $data);
break;
case 'PUT':
curl_setopt($handle, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($handle, CURLOPT_POSTFIELDS, $data);
break;
case 'DELETE':
curl_setopt($handle, CURLOPT_CUSTOMREQUEST, 'DELETE');
break;
}
$response = curl_exec($handle);
$code = curl_getinfo($handle, CURLINFO_HTTP_CODE);
echo curl_getinfo($handle, CURLINFO_CONTENT_TYPE );
echo $code;
print_r ($response);
?>
CURLINFO_CONTENT_TYPE , CURLINFO_HTTP_CODE is working fine but I'm expecting also xml.
Also,
foreach( $response as $obj ):
$output .= '<pre>' . htmlspecialchars( print_r($obj, true) ) . '</pre>';
endforeach;
display anything and give warning as a
Warning: Invalid argument supplied for foreach()
All curl-getinfo functions work well. How can I reach my actual xml data?
That's the print_r($response) output
