[SOLVED] Send an XML EPP request via TCP in PHP

Send an XML EPP request via TCP in PHP

I'm using this code to connect to a registrar via TCP.

stream_socket_client('tcp://registrarwebsite:700', $errno, $errstr, 10, STREAM_CLIENT_CONNECT, $fc)

Connection was successful, as for $fc, I am using stream_context_create to pass SSL certificate and key. At this point, everything works fine.

  $fc = stream_context_create(array(
            'ssl' => array('allow_self_signed' => true,
                'local_cert' => 'ma_registrar_cert.pem',
                'local_pk' => 'ma_registrar_key.pem'
        )));

I want to add an XML request to stream_context_create, to send XML EPP requests to the distant server.

How to do that?

Edit

This is an example of the XML request I want to send to the server along with the stream context.

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>     
<epp xmlns="urn:ietf:params:xml:ns:epp-1.0"> 
  <command> 
    <create> 
      <domain:create xmlns:domain="urn:ietf:params:xml:ns:domain-1.0"> 
        <domain:name>testdomain.com</domain:name> 
        <domain:period unit="y">testdomain.com</domain:period> 
        <domain:registrant>John Doe</domain:registrant> 
      </domain:create> 
    </create> 
    <clTRID>reference</clTRID> 
  </command> 
</epp>

Solution

See my other answer here: https://stackoverflow.com/a/47982304/6368697 to your related question. You basically do not implement the EPP protocol correctly.
