Question

I’m about to connect to a secure EPP server and send an XML request and then receive a response in XML format again.

I need to do this in PHP. So I need to connect to the EPP server on a specific port over TCP, using SSL Certificate (as this is the information I have so far, still waiting to whitelist my IP and send me the certificate).

So my question might seem a little dumb, but do I need to use fsockopen or cURL to connect, how do I define that I need to use SSL and how do I define and use this SSL certificate along with that?

Well, you just init curl, set options and exec curl request:

$url="your_url";
$handle = curl_init(); 
curl_setopt($handle, CURLOPT_URL,$url); 
curl_setopt($handle, CURLOPT_SSLCERT, $sslcertpath); //$sslcertpath - path to your certificate file
curl_setopt($oCurl, CURLOPT_SSL_VERIFYPEER, true); //may want to set false for debugging
//[...]
$response = curl_exec($handle);
curl_close($handle);

var_dump($response);

You can find a complete list of curl options in the manual:
