PHP Curl GET call troubleshooting - php

Question

I am building a website that makes standard HTTP calls to an API. My first call is a straight-forward GET with no parameters using basic auth. I am using Curl in my php. I am running this via a local install of XAMPP. My call is not working but if i have a colleague run the php on his Linux box running an older version of ubuntu PHP it works fine. What is the best way to troubleshoot this issue? My guess is it is something with my XAMPP install but is there a good method for troubleshooting? I have used curl_getinfo on my curl session to get the return values and it doesn't seem to provide much insight as far as I can tell.
Here is the curl_getinfo output:
Array (
[url] => https://www.ebusservices.net/webservices/hrpcertws/rbs/api/merchants/267811683882/consumers.xml?

Added Code:
<?php

// Get the XML from the response, bypassing the header

//echo 'in xml';
}
// Output the XML
echo htmlspecialchars($xml, ENT_QUOTES);
?>

Try using Fiddler to see exactly what is in the HTTP traffic.
