Signing soap header

Question

I started studying web services between bank and a client and I run into a wall when it came to signing a SOAP. What I need should look something like this

<soapenv:Envelope xmlns:cor="http://bxd.fi/CorporateFileService" xmlns:mod="http://model.bxd.fi" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"&gt;
<soapenv:Header>
    <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"&gt;
        <wsse:BinarySecurityToken EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary" ValueType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509v3" wsu:Id="CertId-9502902" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"&gt;

        <ds:Signature Id="Signature-12345678" xmlns:ds="http://www.w3.org/2000/09/xmldsig#"&gt;

                <ds:Reference URI="#id-4453123">
                    <ds:Transforms>

            </ds:SignedInfo>
            <ds:SignatureValue>m5fuzJnVOQGNsu4s2kfaI+UTReUSz9pMxH…=</ds:SignatureValue>
            <ds:KeyInfo Id="KeyId-98765432"><wsse:SecurityTokenReference wsu:Id="STRId-33454994" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"&gt;
                <wsse:Reference URI="#CertId-9502902" ValueType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509v3"/&gt;
                </wsse:SecurityTokenReference>
            </ds:KeyInfo>
        </ds:Signature>
    </wsse:Security>
</soapenv:Header>

My question is how can I sign soap message in PHP? I guess there is some better way than just manually adding headers? I managed to sign xml document that is sent in envelopes body but I'm totally lost with signing the SOAP itself.
