SOAP in PHP5 With Client Certificate Authentication

I think there isn't yet a support for certificate in the SOAP extension in PHP5. I've checked the SOAP sources to see if it's possible to bypass ssl using curl but can't see how to do it ! anyway, I just know that  with PEAR SOAP, you can do something like this :

<?php

$ClientCode = "ClientCode";
$UserID = "UserID";
$UserPassword = "password";
$params = array('ClientCode'=>$ClientCode, 'UserID'=>$UserID,'UserPassword'=>$UserPassword);
$client = new SOAP_Client( "https://secure.someservice.net/path_to_soap_server");

// bypass SSL certificate with CURL
$client->setOpt('curl', CURLOPT_VERBOSE, 1);
$client->setOpt('curl', CURLOPT_POST, 1);
$client->setOpt('curl', CURLOPT_SSL_VERIFYPEER, 0);
$client->setOpt('curl', CURLOPT_SSL_VERIFYHOST, 0);


$response = $client->call(....);

if (strtolower(get_class($response)) == "soap_fault") {
      print "Error! " . $response->message;
}else {
      print "{". print_r($response) ."}";
}

?>


Hope this will help
