Converting from XML to PHP

Question

I am writing PHP soap client. I used wsdlbrowser to format the soap request correctly.

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://ws.iws.iaeste.net/">
  <SOAP-ENV:Body>
    <ns1:fetchOffers>
      <token>
                <token>..your token..</token>
      </token>
      <request>
        <exchangeYear>2015</exchangeYear>
        <fetchType>SHARED</fetchType></request>
    </ns1:fetchOffers>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

This would be correctly formatted soap request. Or to be specific, the code beetwen first token tag and last request tag is in the point of interest.
How would I transfer this request to PHP for sending it over SOAP?
