Retrieve multiple fields in a single request with Facebook PHP SDK

Upon user registration I fetch the users data (name, birthday, location, etc) and also the users profile image.

Currently, I would be able to do this: /me?fields=picture,name, but the picture returned is too low resolution, so I'd like to fetch the picture with the height parameter (as described here).

My only option, as I see it, is to part it up in two requests, which seems inefficient:

Would there be a way to merge this into ONE request?

Use field expansion, just one API call:

/me?fields=name,picture.width(500).height(500),birthday

API Explorer test: https://developers.facebook.com/tools/explorer/?method=GET&path=me%3Ffields%3Dname%2Cpicture.width%28500%29.height%28500%29&version=v2.2

More information about field expansion: https://developers.facebook.com/docs/graph-api/using-graph-api/v2.2#fieldexpansion

Batch Requests would be another solution, although not a very good one in that case because they are a lot more complicated (more code, more things to consider) and they don´t count as one call:

each call within the batch is counted separately for the purposes of calculating API call limits and resource limits

...meaning, they are only faster than 2 separate calls (as fast as the slowest call in the batch), but field expansion is really just 1 call. Batch Requests are for "potentially unrelated Graph API calls".

You can use batch as per the docs here

Here's an example request for your needs:

URL: https://graph.facebook.com/v2.2/

POST data (important! not GET!):

batch=[{"method":"GET", "relative_url":"me/?fields=name"},{"method":"GET", "relative_url":"me/picture?height=500&redirect=false"}]

Optional but recommended: include_headers=false

Example response:

[
  {
    "code": 200,
    "body": "{\n \"name\": \"Richard Down\",\n \"id\": \"704787476294950\"\n}"
  },
  {
    "code": 200,
    "body": "{\n \"data\": {\n \"height\": 604,\n \"is_silhouette\": true,\n \"url\": \"https://fbcdn-profile-a.akamaihd.net/hprofile-ak-xap1/t31.0-1/s960x960/10506738_10150004552801856_220367501106153455_o.jpg\",\n \"width\": 960\n }\n}"
  }
]

EDIT: As you've tagged this with , here's an example using that:

$requests = array(
    array('method' => 'GET', 'relative_url' => 'me/?fields=name'),
    array('method' => 'GET', 'relative_url' => 'me/picture?height=500&redirect=false')
);

$response = json_decode($facebook->api('?batch=' . json_encode($requests), 'POST'), true);

$name = $response[0]['name'];
$image = $response[1]['url'];
