Need to add a configuration file twice

This problem has been worrying me since 2 weeks.

Code :- 

<?php
session_start();
include '../dbconnector.php';

function getRandUsername()
{
    include '../dbconnector.php';
    $u = rand(0,99999);
    //check if the number exists in the database already
    $query="SELECT * from admin where username = '" . $u . "'";
    $result=mysql_query($query,$db) or die (mysql_error($db));
    if(mysql_num_rows($result) > 0)
    {
        echo "Username Exists";
        getRandUsername();
        exit();
    }
    else
    {
        echo "Username Does not exist";
    }
}

getRandUsername();

?>

Problem :- The problem is, that I need to include this dbconnector.php file twice. If I don't include it within the function parentheses, it would throw an error. While if the file is include in the function block, everything works fine.

What's wrong in here?

Thanks.

Try the following:

require_once '../dbconnector.php';

function getRandUsername() {
    global $db;    // where I'm assuming that $db is defined in the external file
