// This is where we will set up the script

// SCRIPT FUNCTION
// The first function defines whether we are using a whitelist or a blacklist
// 1) Whitelist: Only the IP's in the list may pass
// 2) Blacklist: The IP's in the list may not pass
$var_2banornot2ban_function = 2;
// Default: $var_2banornot2ban_function = 2;

// ADMINISTRATOR E-MAIL
// Please fill in the admin's e-mail address below
$var_2banornot2ban_admin = 'Gerard@monstagames.nl';
// Default: $var_2banornot2ban_admin = 'Gerard@monstagames.nl';

// DATA FOLDER
// The next variable contains the path to the 'data' folder of this script
// You can use both an absolute or relative path, your call
// If your website uses lots of (sub)folders, you could include your domain name
// Do not start with a slash, but do end with one!
// Use '..' to go up one folder
// If you wish to use our (remote) files in stead of your own local ones, use this value:
// $var_2banornot2ban_folder = 'http://80.61.36.70/2banornot2ban/data/';
// Do keep in mind that this might slow down the loading of your pages
$var_2banornot2ban_folder = 'data/';
// Default: $var_2banornot2ban_folder = 'data/';

// LIST FILE
// Change this value if you prefer to rename the name of the 'list' file
// You may also give it any extension, so you could name it, for example: 'black.list'
// This file should, however, be placed in the 'data' folder
$var_2banornot2ban_file = 'list';
// Default: $var_2banornot2ban_file = 'list';

// LOCKED FILE
// When a user is refused access to the page, the 'locked' page is displayed
// You may edit the 'locked' file just as you wish to, and you can change its name here
// Just as the 'list' file, the file should remain in the 'data' folder
$var_2banornot2ban_locked = 'locked.php';
// Default: $var_2banornot2ban_locked = 'locked.php';

/* ---------- ENDING OF THE GLOBAL CONFIGURATION ---------- */


// Warning: Do not edit anything from this point unless you know what you are doing!
// Load the IP addresses in the 'list' file into an array
$var_2banornot2ban_list = file($var_2banornot2ban_folder.$var_2banornot2ban_file);
