I am using SOAP call response headers to sign request results.

After alot of hours, I finally got the best way to get SOAP response headers (other than parsing __getLastResponse() witch requires trace option enabled) is using __soapCall() wrapper.

You can extend SoapClient class and wrap some functions to make sure you get the headers.

<?php

class API extends SoapClient
{

    // ... Constructor, etc.

    // Get SOAP Server response headers
    public function __soapCall($function, $arguments, $options = array(), $input_headers = null, &$output_headers = null)
    {
        parent::__soapCall($function, $arguments, $options, $input_headers, $output_headers);

        print_r($output_headers); // Array of response headers
    }

    // If you are using WSDL you need this, so you still can call functions directly without calling __soapCall manualy
    public function __call($func, $args)
    {
        return $this->__soapCall($func, $args);
    }

?>
