如何使用SOAP XML服务PHP？

I am completly new to SOAP.

I have been provided with an XML document (SOAP) to send data and receive response.

here is the xml document XML.

Target="Production"
Version="1.002">
  <AvailStatusMessages HotelCode="ATLPE" HotelName="The Sheraton">
  <AvailStatusMessage BookingLimit="25"
  BookingLimitMessageType="SetLimit">
  <StatusApplicationControl Start="2011-12-02"
  End="2011-12-05"
  RatePlanCode="WHLS1" InvCode="STD">
 </StatusApplicationControl>
<UniqueID Type="16" ID="1">
</UniqueID>
</AvailStatusMessage>
<AvailStatusMessage BookingLimit="35"
BookingLimitMessageType="SetLimit">
<!-- Content omitted -->
</AvailStatusMessage>
</AvailStatusMessages>
</OTA_HotelAvailNotifRQ>
