VBulletin code is required for guests to see what is it?

Hi,

vBulletin these codes

PHP Code:

error_reporting(E_ALL & ~E_NOTICE);
require_once('./global.php'); 


I'm just used to run them

PHP Code:

$field_alani = $vbulletin->options['tc_kimlik_no_kontrolu_field'];

$tc_no = $vbulletin->input->clean_gpc('p', 'tc_no', TYPE_NOHTML);

$tc_no_sorgula = $db->query_read("SELECT * FROM " . TABLE_PREFIX . "userfield WHERE $field_alani LIKE '$tc_no'"); 


My special number codes on them all

PHP Code:

error_reporting(E_ALL & ~E_NOTICE);

require_once('./global.php');

$field_alani = $vbulletin->options['tc_kimlik_no_kontrolu_field'];

$tc_no = $vbulletin->input->clean_gpc('p', 'tc_no', TYPE_NOHTML);

$tc_no_sorgula = $db->query_read("SELECT * FROM " . TABLE_PREFIX . "userfield WHERE $field_alani LIKE '$tc_no'");    

if(mysql_num_rows($tc_no_sorgula))
{
echo 'No';

}
else
{
echo 'OK';
} 


The problem that:

Guests are allowed to give the code for what?
What code is required to use vBulletin?
