FreeAgent oAuth2 can't update contact using Light PHP wrapper - php

Question

I’m having problems creating a new contact in FreeAgent.
I’m using the Light PHP wrapper for the OAuth 2.0 protocol and have managed to successfully set up oAuth2. I can connect to FreeAgent and successfully retrieve a list of customers. So far, so good. The problem I’ve got is sending data back the other way, i.e. creating a new contact in FreeAgent.
Here’s some code I’ve tried:
require_once($_SERVER['DOCUMENT_ROOT'].'/OAuth2/Client.php');
require_once($_SERVER['DOCUMENT_ROOT'].'/OAuth2/GrantType/IGrantType.php');
$client = new OAuth2\Client($clientid, $secret);
$params = json_encode(array('contact' => array('first-name' => $firstname_unencrypted, 'last-name' => $surname_unencrypted)));
$response = $client->fetch("/contacts", $params, "POST", array('User-Agent' => 'MyApp', 'Accept' => 'application/json', 'Content-type' => 'application/json'));
var_dump($response);
The var_dump returned shows:
array(3) {
["result"]=>
bool(false)
["code"]=>
int(0)
["content_type"]=>
bool(false)
}
I’m pretty sure I’m doing something silly. I’ve tried sending in XML instead of JSON. I’ve tried using just a single array of params rather than the array in an array I’ve got in the sample. I’m going round in circles!
If someone could give me a little nudge in the right direction, I’d be eternally grateful!

Sample code that worked:
$xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<contact>
<first-name>$firstname_unencrypted</first-name>
<last-name>$surname_unencrypted</last-name>
</contact>";
if ($sandbox || $demo)
$ch = curl_init('https://api.sandbox.freeagent.com/v2/contacts');
else
$ch = curl_init('https://api.freeagent.com/v2/contacts');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Authorization: Bearer '.$freeagentaccesstoken,
'Content-Type: application/xml',
'Accept: application/json',
'User-Agent: MyApp',
'Content-Length: ' . strlen($xml))
);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
//execute post
$result=json_decode(curl_exec($ch), true);
$freeagenturl=$result['contact']['url'];
curl_close($ch);
