Add security to included files

[dynamiccookies]

Set defined variable before including file Check for defined variable in included file, and return permission denied error if does not exist Unset defined variable after including file

Example Code

In Calling File:

$included = true;
require_once('called_file.php');
$included = false;

In Called File:

if (!$included) {
  header('HTTP/1.0 403 Forbidden');
  exit;
}

Decided on slight change to process.

In Calling File:

$include = true;
require_once 'admin/config.php';

$include = true;
require_once 'files/functions.php';

In Called File:

if (!isset($include)) {
    header('HTTP/1.0 403 Forbidden');
    exit;
} else {unset($include);}
