使用PHP在調用soap中添加自定義HTTP標頭

我試圖連接到WebService SOAP。服務要求我們在SOAP調用使用PHP在調用soap中添加自定義HTTP標頭

$context = array('http' => 
    array(
     'header' => "APIToken: $api_token\r\n" 
    ) 
); 
$soap_options = array(
    'stream_context' => stream_context_create($context), 
    'encoding' => 'UTF-8', 
    'exceptions' => TRUE, 
    'trace' => true, 
    'local_cert' => 'mycert.pem', 
    'passphrase'=>'xxx', 
    'location'=>$this->url_soap_dev 
); 

$soap_client = new SoapClient('soap.wsdl', $soap_options); 

$args = array(
    'param1' => $var, 
    'param2' => 0, 
    'optionalParameters'=>array() 
); 

$ret = $soap_client->RemoteFunction(array('parameter'=>$args));

的HTTP標頭添加自定義的參數，這是我的請求報頭：

POST /server/soap HTTP/1.1 
Host: domain.com 
Connection: Keep-Alive 
User-Agent: PHP-SOAP/5.2.6-1+lenny16 
Content-Type: text/xml; charset=utf-8 
SOAPAction: "" 
Content-Length: 400

我在哪裏可以添加自定義PARAM？

Thx。
