How to use PHP Guzzle to make a batch request?

// plain

PHP Guzzle can be used to make batch requests. This is done by creating an array of requests and passing it to the send() method of the GuzzleHttp\Client class.

$client = new GuzzleHttp\Client();
$requests = [
    'req1' => $client->getAsync('http://httpbin.org/get'),
    'req2' => $client->getAsync('http://httpbin.org/get?foo=bar'),
    'req3' => $client->getAsync('http://httpbin.org/get?baz=bam')
];
$results = GuzzleHttp\Promise\unwrap($requests);

The output of the above code will be an array of responses:

Array
(
    [req1] => GuzzleHttp\Psr7\Response Object
        (
            [reasonPhrase:GuzzleHttp\Psr7\Response:private] => OK
            ...
        )
    [req2] => GuzzleHttp\Psr7\Response Object
        (
            [reasonPhrase:GuzzleHttp\Psr7\Response:private] => OK
            ...
        )
    [req3] => GuzzleHttp\Psr7\Response Object
        (
            [reasonPhrase:GuzzleHttp\Psr7\Response:private] => OK
            ...
        )
)

Code explanation

1. $client = new GuzzleHttp\Client(); - This creates a new instance of the GuzzleHttp\Client class.
2. $requests = [ ... ] - This creates an array of requests.
3. $results = GuzzleHttp\Promise\unwrap($requests); - This sends the requests and returns an array of responses.
