PHP curl and outputting api responses - php

Question

I am using cURL to interface with an API. What I wanting to do once I done what I need to with API is output the APIs response.
<?php
/*
* Server REST - user.login
*/
$input = file_get_contents("php://input");
$xml_input = simplexml_load_string($input);
$xml_arr = json_decode(json_encode($xml_input, TRUE));
// REST Server URL
$request_url = 'http://xxx.localhost:8888/api/v1/user/login.json';
// User data
$user_data = array(
'username' => $xml_arr->Username,
'password' => $xml_arr->Password,
);
// cURL
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $request_url);
curl_setopt($curl, CURLOPT_POST, 1); // Do a regular HTTP POST
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Accept: application/json', 'Content-Type: application/json'));
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($user_data)); // Set POST data
curl_setopt($curl, CURLOPT_HEADER, FALSE); // Ask to not return Header
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($curl, CURLOPT_FAILONERROR, TRUE);
$response = curl_exec($curl);
$http_code = curl_getinfo($curl, CURLINFO_HTTP_CODE);
if ($http_code == 200) {
$logged_user = json_decode($response);
}
else {
$http_message = curl_error($curl);
return http_response_code(401);
}
$cookie_session = $logged_user->session_name . '=' . $logged_user->sessid;
if($xml_arr->Action == "Delete"){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://xxx.localhost:8888/api/v1/logic_melon/' . $xml_arr->JobReference);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/json', 'Content-Type: application/json', 'X-CSRF-Token: ' . $logged_user->token, 'Cookie: ' . $cookie_session));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
} elseif($xml_arr->Action == "Add") {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'http://xxx.localhost:8888/api/v1/logic_melon');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/json', 'Content-Type: application/json', 'X-CSRF-Token: ' . $logged_user->token, 'Cookie: ' . $cookie_session));
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($xml_arr));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
}
$response = curl_exec($ch);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($http_code == 200)
{
// Convert json response as array
$response = json_decode($response);
echo $response;
}
else
{
// Get error msg
$http_message = curl_error($curl);
}
The api returns a response code and an message, how would I output this to my user? return $response doesn't seem to do the job.
