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.
