Send POST Batch Request From PHP

Question

Measurement protocol docs give me these directions to send a batch request:

POST /batch HTTP/1.1
Host: www.google-analytics.com

v=1&tid=UA-XXXXX-Y&cid=555&t=pageview&dp=%2Fhome
v=1&tid=UA-XXXXX-Y&cid=555&t=pageview&dp=%2Fabout
v=1&tid=UA-XXXXX-Y&cid=555&t=pageview&dp=%2Fcontact

Im a little confused on how i would build my url for this?

What i have tried:

$guzzle = new \GuzzleHttp\Client();
$guzzle->request('POST','www.google-analytics.com/batch',[
                'query' =>  "v=1&tid=UA-XXXXX-Y&cid=555&t=event
                             v=1&tid=UA-XXXXX-Y&cid=555&t=event
                             v=1&tid=UA-XXXXX-Y&cid=555&t=event
                             v=1&tid=UA-XXXXX-Y&cid=555&t=event
                             v=1&tid=UA-XXXXX-Y&cid=555&t=event"
            ]);

This does not work, there should 5 new events in ga, but i only receive 1 (the first one).

How can i send a batch request to the measurement protocol?

If you use GuzzleHttp, you should use body instead of query:

$guzzle = new \GuzzleHttp\Client();
$guzzle->request('POST','www.google-analytics.com/batch', [
        'body' => implode("\n", array(
                        'v=1&tid=UA-XXXXX-Y&cid=555&t=event',
                        'v=1&tid=UA-XXXXX-Y&cid=555&t=event',
                        'v=1&tid=UA-XXXXX-Y&cid=555&t=event',
                        'v=1&tid=UA-XXXXX-Y&cid=555&t=event',
                        'v=1&tid=UA-XXXXX-Y&cid=555&t=event',
        )]);
