Cpanel Username Var

[tarleton]

Hello I am tryin to get this script to run automatically after payment, I was wondering what file do i need to include into this script to make the variable $cpanel_user for example. He is the code:

# cPanel Database Creator 1.2
###############################################################
# Visit http://www.zubrag.com/scripts/ for updates
############################################################### 

// cPanel username (you use to login to cPanel)
$cpanel_user

// cPanel password (you use to login to cPanel)
$cpanel_password

// cPanel domain (example: mysite.com)
$cpanel_host = "localhost";

// cPanel theme/skin, usually "x"
// Check http://www.zubrag.com/articles/determine-cpanel-skin.php
// to know it for sure
$cpanel_skin = "x";

// Script will add user to database if these values are not empty
// User wil have ALL permissions
$db_username = '';
$db_userpass = '';

// Update this only if you are experienced user or if script does not work
// Path to cURL on your server. Usually /usr/bin/curl
$curl_path = "";

//////////////////////////////////////
/* Code below should not be changed */
//////////////////////////////////////

function execCommand($command) {
 global $curl_path;

 if (!empty($curl_path)) {
   return exec("$curl_path '$command'");
 }
 else {
   return file_get_contents($command);
 }
}

if(isset($_GET['db']) && !empty($_GET['db'])) {
 // escape db name
 $db_name = escapeshellarg($_GET['db']);

 // will return empty string on success, error message on error
 $result = execCommand("http://$cpanel_user:$cpanel_password@$cpanel_host:2082/frontend/$cpanel_skin/sql/adddb.html?db=$db_name");

 if(isset($_GET['user']) && !empty($_GET['user'])) {
   $db_username = $_GET['user'];
   $db_userpass = $_GET['pass'];
 }

 if (!empty($db_username)) {
   // create user
   $result .= execCommand("http://$cpanel_user:$cpanel_password@$cpanel_host:2082/frontend/$cpanel_skin/sql/adduser.html?user={$db_username}&pass={$db_userpass}");
   // assign user to database
   $result .= execCommand("http://$cpanel_user:$cpanel_password@$cpanel_host:2082/frontend/$cpanel_skin/sql/addusertodb.html?user={$cpanel_user}_{$db_username}&db={$cpanel_user}_{$db_name}&ALL=ALL");
 }

 // output result
 echo $result;
}
else {
 echo "Usage: cpanel_create_db.php?db=databasename&user=username&pass=password";
}
