Via Composer

$ composer require africc/php-epp2


See the examples folder for a more or less complete usage reference. Additionally have a look at whmcs-registrars-coza which is a WHMCS Registrar Module for the zone using this library.

Basic Client Connection

this will automatically login on connect() and logout on close()

require 'vendor/autoload.php';

use AfriCC\EPP\Client as EPPClient;

$epp_client = new EPPClient([
    'host' => '',
    'username' => 'foo',
    'password' => 'bar',
    'services' => [
    'debug' => true,

try {
    $greeting = $epp_client->connect();
} catch(Exception $e) {
    echo $e->getMessage() . PHP_EOL;


Create Frame Objects

setXXX() indicates that value can only be set once, re-calling the method will overwrite the previous value.

addXXX() indicates that multiple values can exist, re-calling the method will add values.

require 'vendor/autoload.php';

use AfriCC\EPP\Frame\Command\Create\Host as CreateHost;

$frame = new CreateHost;
echo $frame;

// or send frame to previously established connection

Parse Response

You can either access nodes directly by passing through a xpath or use the data() Method which will return an assoc array.

use AfriCC\EPP\Frame\Command\Check\Domain as DomainCheck;
use AfriCC\EPP\Frame\Response;

$frame = new DomainCheck;

$response = $epp_client->request($frame);
if (!($response instanceof Response)) {
    echo 'response error' . PHP_EOL;

$result = $response->results()[0];

echo $result->code() . PHP_EOL;
echo $result->message() . PHP_EOL;
echo $response->clientTransactionId() . PHP_EOL;
echo $response->serverTransactionId() . PHP_EOL;
$data = $response->data();
if (empty($data) || !is_array($data)) {
    echo 'empty response data' . PHP_EOL;

foreach ($data['chkData']['cd'] as $cd) {
    printf('Domain: %s, available: %d' . PHP_EOL, $cd['name'], $cd['@name']['avail']);


  • objectspec on login needs to be smarter (no global/static object, auto-injecter)
  • stricter response parsing
  • stricter request validation
  • make it server capable (in conjunction with apache mod_epp)
