define("MONO_ON");

its in the db class file, login file etc

Re: code line help

define("MONO_ON",1);

include "class/class_db_{$_CONFIG['port']}.php";

I think it is,

If you go look at class_db_mysql.php it says

 

if(define("MONO_ON") != 1)

{

die();

}

Re: code line help

A simple search can help you with that...

 

<?php
define("CONSTANT", "Hello world.");
echo CONSTANT; // outputs "Hello world."
echo Constant; // outputs "Constant" and issues a notice.

define("GREETING", "Hello you.", true);
echo GREETING; // outputs "Hello you."
echo Greeting; // outputs "Hello you."

?>

Re: code line help

It's often used as a mechanism to prevent a file from being executed *unless* it was included from somewhere else.

For example, Assuming the following (and rather daft) file:

 

<?php /* mypass.php */
if (!defined('SECURE_LABEL')) { die("Access Denied"); }
echo "Your password is 'elephant'";
?>

 

Now, if somebody tries to call the file directly - usually by typing the full url into the address bar, they will just see "Access Denied";

In order to gain access to that file, you could do:

 

<?php /* mysecurepass.php */
define('SECURE_LABEL', true);
include("mypass.php");
?>

 

Now, if anybody navigates to mysecurepass.php, the mypass.php will be include, but this time, as SECURE_LABEL was defined, it will actually show your password.

For obvious reasons, DON'T DO THIS, however it does hopefully exhibit how using manifest constants (in your case MONO_ON, in mine SECURE_LABEL) can be used to provide a limited for of protection.

Personally, I find little need for this type of protection, however there are a lot of scripts that use it.

Re: code line help

I used this way on my ptc to stop the some script's from outsider's.

I also used this to stop people from going to the config.php as many people were looking for it at some point. Another way is if some one find's a way to exploit your game in uploading a file such as a file that will connect to config.php and then fetch data from it this can be used.

For example:

in config.php:

if(!defined('Config_Connect'))
{
   die("Your not allowed to be here");
}
else
{
   $_CONFIG = array(.....);
}

 

Then in register.php, globals.php, fpass.php, login.php You add

 

define("Config_Connect");

 

It's just another way to secure some script's from outsider's.
