How can I receive this request in another server using curl and php

Question

I'm new here so please be patient, This is my request code, I want to write another piece of code in another server that will be accepting it and returning an xml 7101 success code using php and curl. How do I write code in a receiving server. This is actually API that I will be using to exchange data between my system and another remote system stored in clouds I have managed to send request successfully but I have stuck at receiving their requests, I have spent an entire week on it please help me out on receiving the requests when they send them to me.

success code is

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<gepgBillSubReqAck>
    <TrxStsCode>7101</TrxStsCode>
</gepgBillSubReqAck>

the request code is this,

<?php

    //Bill Request 
    $content ="<gepgBillSubReq>
        <BillHdr>
            <SpCode>SP103</SpCode>

Thanks, you guys for contributing I found a solution, I used file_get_contents("php://input"); on the receiving server and so far it is working fine.
