159755 PHP web service integration

I am trying to send an xml document to Fedex web services (rateavailableservices.) The problem is that I always recieve an empty response from the Fedex server. I cannot use the SOAP services to establish a connection because it is not supported in PHP4. FedEx offers a non-SOAP Web Service solution that you can use to send transactions directly to FedEx, without having to use tools that provide SOAP protocol support for Web Services. This may be convenient for developers using environments that do not provide support for SOAP. With this interface XML documents are directly sent to the FedEx servers via the HTTP POST command as shown in Error HandlingError Handling. FedEx provides a set of specifications and examples to help with the development of this type of application. To use the non-SOAP Web Service solution, you must meet the following requirements: * A working knowledge of HTTPS and Secure Socket Layering encryption * The ability to provide a secure SSL connection to FedEx. The ability to code to a designated transactional interface using XML I have all the functions needed above to query the Fedex server- all you need to do is recieve a positive response. I think I am 99% percent but dont know what I am doing wrong! I will email the files to you once you bid. Thanks!
