JSON POST request - Pocket API / OAuth2.0

Question

I'm attempting to build an application that interfaces with Pocket using PHP and JQuery

Following the steps here http://getpocket.com/developer/docs/authentication I'm stuck on "Step 2: Obtain a request token"

The documentation tells me this:

POST /v3/oauth/request HTTP/1.1
Host: getpocket.com
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
X-Accept: application/x-www-form-urlencoded

consumer_key=1234-abcd1234abcd1234abcd1234&
redirect_uri=pocketapp1234:authorizationFinished

This makes no sense to me. How do I format this OAuth JSON POST request to use PHP and/or JQuery?

Note, I've attempted to use https://github.com/jshawl/pocket-oauth-php, but it fails on the callback and seems to use GET while the documentation explicitly states POST. I'd also like to figure this out myself so I can learn how to use OAuth for other APIs.

Thank you.

this seems to work ok:

<?php
session_start();
$redirect_uri = 'http://path/to/app/callback';
$url = 'https://getpocket.com/v3/oauth/request';
$data = array('consumer_key' => '*****', 'redirect_uri' => $redirect_uri);

// use key 'http' even if you send the request to https://...
$options = array(
    'http' => array(
        'header'  => "Content-type: application/x-www-form-urlencoded; charset=UTF-8",
        'method'  => 'POST',
        'content' => http_build_query($data),
    ),
);
$context  = stream_context_create($options);
$result = file_get_contents($url, false, $context);

$request_token = str_replace('code=','',$result);

$_SESSION['request_token'] = $request_token;

header("Location: https://getpocket.com/auth/authorize?request_token=$request_token&redirect_uri=$redirect_uri");
die();

?>

After which I use the request_token in the session to get my access token in a similar way.
