PHP SOAP Communication Using TLS 1.2

Question

We have integrated UPS Web Service in our site. recently we got alert from UPS :

Effective January 26, 2016,the UPS test environment will require the TLS 1.2 security protocol, and willbe available for your system testing.

Effective May 31, 2016,UPS will require the TLS 1.2 security protocol in production. After that date,any communication requests submitted to UPS using older protocols (TLS 1.1 orearlier) will fail.

My question is :

Is there any way to communicate PHP SOAP using TLS ? i have already googled a lot but could not find any solution yet.

Please suggest

Answer 1

I met this problem too. I use this to force TLS communication.

$mode = array
(
    'soap_version' => 'SOAP_1_1',  // use soap 1.1 client
    'trace' => 1,
    'stream_context' => stream_context_create(array(
        'ssl' => array(
            'crypto_method' =>  STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT,
        )
     ))
);

// initialize soap client
$client = new SoapClient($this->wsdl, $mode);

But I have always a problem (on my dev environment) with MAMP witch includes a version of openssl without TLS 1.2 support.

Finally i got solution for this issue.It require OpenSSL > 1.0.1 or NSS > 3.15 and in my case our server support SSL Version is NSS/3.19.1 Basic ECC so no need to change any code.
