how to send post request by curl to web services in php

Question

I need to fetch data from myallocator.com. I have his api address api.myallocator.com, but when I send my data to them, it failed. I wrote some code for that which is shown below. Basically that pms property management system site.By that you can manage your property with his api.

    $url = "http://api.myallocator.com/";

    $xmlRequestString='<?xml version="1.0" encoding="UTF-8"?>
    <GetProperties>
      <Auth>
        <UserId>"xxxxxxx"</UserId>
        <UserPassword>"xxxxx"</UserPassword>
        <VendorId>"xxxxxxx"</VendorId>
        <VendorPassword>"xxxxxxxx"</VendorPassword>
      </Auth>
    </GetProperties>';

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_POSTFIELDS,  $xmlRequestString);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_VERBOSE, 0);
    $data = curl_exec($ch);
    echo $data;
    curl_close($ch);
