EDIT:
Replace the code in your connection script with code below and save it as config.php:

<?php
class DBController {
    private $host = "localhost";
    private $user = "DBUSERNAME"; //Replace with your own db username
    private $password = "DBPASSWORD"; //Replace with your own db password
    private $database = "DBNAME"; //Replace with your own db name

    function __construct() {
        $conn = $this->connectDB();
        if(!empty($conn)) {
            $this->selectDB($conn);
        }
    }

    function connectDB() {
        $conn = mysql_connect($this->host,$this->user,$this->password);
        return $conn;
    }

    function selectDB($conn) {
        mysql_select_db($this->database,$conn);
    }

    function runQuery($query) {
        $result = mysql_query($query);
        while($row=mysql_fetch_assoc($result)) {
            $resultset[] = $row;
        }       
        if(!empty($resultset))
            return $resultset;
    }

    function numRows($query) {
        $result  = mysql_query($query);
        $rowcount = mysql_num_rows($result);
        return $rowcount;   
    }
}
?>

Then in your other scripts you're going to include the config.php like below:

<?php require_once("folder_where_config.php_is_located/config.php"); ?>
<?php
    if(empty($_GET['p'])) {
        $_GET['p']='home';
    }
    if(empty($_GET['page'])) {
        $_GET['page']='1';
    }
    if(empty($_GET['l'])) {
        $_GET['l']='english';
    }
?>

What I would then recommend is trying something like this for the login, of course you can modify this to your liking later and keep in mind you don't actually wanna use the code below because mysql is deprecated:

 <?php
    require_once("config.php");
    $db_handle = new DBController();


    if(!empty($_POST['username']) && ($_POST['password'])) {
        $result = mysql_query("SELECT count(*) FROM users WHERE Username=BINARY'".$_POST['username']."' AND password=BINARY'".$_POST['password']."'"); //You would use BINARY to make sure that the values match word for word, letter by letter, etc
        $row = mysql_fetch_row($result);
        $user_count = $row[0];
        if($user_count<1) {
            echo "error";
        } else {
        //place login function here
        }
    }
?>
