TLS v1.2 ciphers to use in PHP NUSOAP SoapClient

Question

I want to connect to a server that only supports TLS 1.2. What possible ciphers can I specify to stream context in the PHP NUSOAP SoapClient creation?

<?php
    $objSoapClient = new SoapClient(
        "https://example.com/?wsdl",
        array(
            "encoding"=>"ISO-8859-1",
            "stream_context"=>stream_context_create(
                array(
                    "ssl"=>array("ciphers"=>"<????>")
                )
            )
        )
    );
?>

Your answer below is OK for PHP SoapClient. I am also looking for a way to do the same using PHP NUSOAP API. — Kartins, Feb 27 '17 at 10:26

TLS v1.2 is described in RFC5246, you can read it here. List of ciphers you can find in openssl wiki, use the second line without trailing 256. You can manually get a list of ciphers used by running openssl ciphers -v | grep -v 'TLSv1.2' on the server in case you have access to it.

$context = stream_context_create(
    [
        'ssl' => [
            'ciphers' => 'DHE-RSA-AES256-SHA:DHE-DSS-AES256-SHA:AES256-SHA',
        ],
    ]
);
