Connecting to domain registry EPP server

I'm getting my sea legs and need some pointers and a small sample of code that connects to an epp server. The sample of code need to login and send one command and receive a response.(in XML). Code can be in php or python.

This I believe will form a basis/kickstart for me to delve in further and learn more about this topic. It's driving me up the wall - in a good way as I want to solve it in one day or a thousand.

And I have been searching for days now but can't seem to make sense of the info found, and now opted to ask here for guidance.

Thank you in advance.

This is sample php script

<?php


class Epp 
{

var $socket;

public function __construct()
{
}


private $_connected = false;

function connect($host, $port = 700, $timeout = 1, $ssl = true)
{
    if ($this->_connected)
        return true;
    $target = sprintf('%s://%s', ($ssl === true ? 'ssl' : 'tcp'), $host);
    $socket = fsockopen($target, $port, $errno, $errstr, $timeout);
    if (!$socket) {
        return new PEAR_Error("Error connecting to $target: $errstr (code $errno)");
    } else {
        $this->socket = $socket;
        $this->_connected = true;
        return $this->getFrame();
    }
}


function getFrame()
{
    if (feof($this->socket))
        return new PEAR_Error("Connection appears to have closed.");
    $hdr = @fread($this->socket, 4);
    if (empty($hdr)) {
        return new PEAR_Error("Error reading from server: $php_errormsg");
    } else {
        $unpacked = unpack('N', $hdr);
        $answer = fread($this->socket, ($unpacked[1] - 4));
        return $answer;
    }
}

function sendFrame($xml)
{
    return @fwrite($this->socket, pack('N', (strlen($xml) + 4)) . $xml);
}

function disconnect()
{
    return @fclose($this->socket);
}

}

?>

And there are 4 functions , connect , getFrame , sendFrame , disconnect . Epp protocol works following . Firstly you must connect to server .

Send xml request to server and receive xml response from server .

And firstly you must login to server . for that you must send login xml to server .

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<epp xmlns="urn:ietf:params:xml:ns:epp-1.0"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="urn:ietf:params:xml:ns:epp-1.0
      epp-1.0.xsd">
    <command>
        <login>
            <clID><?php echo $username;?></clID>
            <pw><?php echo $password;?></pw>
            <options>
                <version>1.0</version>
                <lang>en</lang>
            </options>
            <svcs>
                <svcExtension>

                </svcExtension>
            </svcs>
        </login>
        <clTRID>12345</clTRID>
    </command>
</epp>

All request and responses is xml . And you can find xmls from this sites https://www.rfc-editor.org/rfc/rfc5732
