An asynchronous SOAP client build on top of Guzzle. The SoapClient implements meng-tian/php-async-soap.

PHP 7.1 --enablelibxml --enable-soap

composer require meng-tian/async-soap-guzzle

From v0.4.0 or newer, an instance of Psr\Http\Message\RequestFactoryInterface and an instance of Psr\Http\Message\StreamFactoryInterface need to be injected into Meng\AsyncSoap\Guzzle\Factory. These two interfaces are defined in PSR-17 to create PSR-7 compliant HTTP instances. This change will decouple this library from any specific implementation of PSR-7 and PSR-17. Clients can determine which implementation of PSR-17 they want to use. Plenty of different implementations of PSR17 can be found from Packagist, e.g., symfony/psr-http-message-bridge, or laminas/laminas-diactoros.

1. Require this library and an implementation of PSR-17 in your composer.json:

...
    "require": {
        "php": ">=7.1.0",
        "meng-tian/async-soap-guzzle": "~0.4.0",
        "laminas/laminas-diactoros": "^2.0"  # this can be replaced by any implementation of PSR-17
    },
...

2. Run composer install

3. Create your async SOAP client and call your SOAP messages:

use GuzzleHttp\Client;
use Meng\AsyncSoap\Guzzle\Factory;
use Laminas\Diactoros\RequestFactory;
use Laminas\Diactoros\StreamFactory;

$factory = new Factory();
$client = $factory->create(new Client(), new StreamFactory(), new RequestFactory(), 'http://www.webservicex.net/Statistics.asmx?WSDL');

// async call
$promise = $client->callAsync('GetStatistics', [['X' => [1,2,3]]]);
$result = $promise->wait();

// sync call
$result = $client->call('GetStatistics', [['X' => [1,2,3]]]);

// magic method
$promise = $client->GetStatistics(['X' => [1,2,3]]);
$result = $promise->wait();
