ayuda con con una parte de installacion de chat

[droiken]

saludos a todos los miembros de foros del web, soy nuevo en el mundo de la computación, por lo tanto soy novato jeje (hay que decir las cosas por su realidad), lo que necesito ayuda es por que quiero instalar un chat de prueba a mi web, pero hay un paso que no entiendo y espero alguno me pueda ayudar como puedo hacer de forma facil (si necesito algun programa o los pasos a seguir), de antemano muchas gracias, aqui dejo lo que dice el manual de instalacion:

# First you need to create a file called gixawremote_custom.php. It should contain your PHP code with the following flow:

<?php
require_once(realpath(dirname(__FILE__)).DIRECTORY _SEPARATOR.’gixawremote.php’);

if (/* user is not logged in */) {
/*
Show or redirect to the login form of your application.
Once logged in, redirect the user back to the same url, with exactly same querystring.
It’s important that querystring remains the same or return_to_gixaw function won’t work.
*/
}
else {
/*
User is logged in! We need to send it’s information back to
Gixaw installation which sent us here.

The $data array should have the information about the logged in user.
The required keys are given below.
*/
$data = array(
’external_id’ => $user_id,
’display_name’ => $nick_or_display_name,
’group_name’ => $group_name,
);

return_to_gixaw($data);
}

?>

Accepted keys for $data (array passed to return_to_gixaw function).

Required keys:

external_id - this is the integer or string used to uniquely identify this user, usually it would be the “id” field in your database table.
display_name - display name (or nick name) for this user
group_name - group name for this user, if your database does not store group names then it is advised to use Administrator for admin user, Moderator for the selected few and Member for the rest.

Optional keys:

profile_full_name - full name
profile_email_address - email address
profile_dob - date of birth
profile_gender - gender
profile_home_phone - home phone
profile_work_phone - work phone
