implement MTOM SOAP (multipart MIME)

https://en.wikipedia.org/wiki/Message_Transmission_Optimization_Mechanism:

MTOM is the W3C Message Transmission Optimization Mechanism, a method of efficiently sending binary data to and from Web services.

@simevo PHP SoapClient doesn't support anymore MTOM. A simple implementation is:

class MTOMSoapClient extends SoapClient
{
    public function __doRequest($request, $location, $action, $version, $one_way = 0)
    {
        $response = parent::__doRequest($request, $location, $action, $version, $one_way);

        $xml_response = null;

        preg_match('/<soap[\s\S]*nvelope>/', $response, $xml_response);

        if (!is_array($xml_response) || !count($xml_response)) {
            throw new Exception('No XML has been found.');
        }

        $xml_response = reset($xml_response);

        $xop_elements = null;
        preg_match_all('/<xop[\s\S]*?\/>/', $response, $xop_elements);
        $xop_elements = reset($xop_elements);

        if (is_array($xop_elements) && count($xop_elements)) {
            foreach ($xop_elements as $xop_element) {
                
                $cid = null;
                preg_match('/cid:([0-9a-zA-Z-]+)@/', $xop_element, $cid);
                $cid = $cid[1];

                $binary = null;
                preg_match('/Content-ID:[\s\S].+?'.$cid.'[\s\S].+?>([\s\S]*?)--uuid/', $response, $binary);
                $binary = trim($binary[1]);

                $binary = base64_encode($binary);

                $xml_response = preg_replace('/<xop:Include[\s\S]*cid:'.$cid.'@[\s\S]*?\/>/', $binary, $xml_response);
            }
        }

        return $xml_response;
    }
}

Hi and thanks !
Have you tested that this works with the official SdI ?
Can we include this code in this repo and licence it AGPL-3.0 ? A PR would be even better !

yes, it is the same code from https://forum.italia.it/t/sdicoop-configurazione-php-soapclient-per-invio-di-test/5528/5?u=simevo without the ssl implementation.

Can we include this code in this repo and licence it AGPL-3.0 ?

no problem.
