LinkedIn API - Setting user status saying unauthorised - json

Question

So I've been following through various tutorials and documents to get this working and am really struggling. These are the files required for it to work:
Required Files
auth.php
<?php
session_start();
$config['base_url'] = '';
$config['callback_url'] = '';
$config['linkedin_access'] = '';
$config['linkedin_secret'] = '';
include_once "linkedin.php";
# The first step is to initialize with your consumer key and secret. We'll use an out-of-band oauth_callback.
$linkedin = new LinkedIn($config['linkedin_access'], $config['linkedin_secret'], $config['callback_url'] );
//$linkedin->debug = true;
# Now we retrieve a request token. It will be set as $linkedin->request_token.
$linkedin->getRequestToken();
$_SESSION['requestToken'] = serialize($linkedin->request_token);
# With a request token in hand, we can generate an authorization URL, which we'll direct the user to.
//echo "Authorization URL: " . $linkedin->generateAuthorizeUrl() . "\n\n";
header("Location: " . $linkedin->generateAuthorizeUrl()); ?>

This is the script that I get after signup:

# The first step is to initialize with your consumer key and secret. We'll use an out-of-band oauth_callback.

//$linkedin->debug = true; if (isset($_REQUEST['oauth_verifier'])){

The Problem
Trying to set the status
To set the status update I have tried using this in the demo.php file:
$setStatus = "Testing API";
$statusResponse = $linkedin->setStatus("~:($setStatus)");
echo '<pre>';
var_dump($statusResponse);
echo '</pre>';
But it is giving me this error:
Setting status... ~:(Testing API)
string(343) "
401
1407931633217
DW74ALZZVN
0
[unauthorized]. OAU:xxxxxxxxxxxxxxxxxx|xxxxxxxxxxxxx|*01|*01:1407931633:eyA6PiJzKUJixQLLtaQL90wppHI=
"
P.S: I x'd out the key there, but they are correct and the rest of the script works with them.
How do I set the status of the authorised account? So I've been following through various tutorials and documents to get this working and am really struggling. These are the files required for it to work:

Answer 1

Not sure if it is still relevant, and the current-status API is deprecated, but the line:
$xml = "<current-status>" . htmlspecialchars($status, ENT_NOQUOTES, "UTF-8") . "</current-status>";
needs to be changed to:
$xml = "" . htmlspecialchars($status, ENT_NOQUOTES, "UTF-8") . "";
