You can use Session to control whether the user is logged in or not, here's an example of how you could do this control.

PHP

class auth
{
    public static function logged($url)
    {
        if(!$_SESSION['logged'])
            header("location :".$url);          
    }

    public static function login($username, $password)
    {
        if($username == "usuario" && $senha == "senha")
            $_SESSION['logged'] = true;
        else
            return false;

        return true;
    }

    public static function logout()
    {
        if($_SESSION['logged'])
            unset($_SESSION['logged']);
    }   
}

And to make the control on your page do this.

PHP

auth::logged("/login");

You may be using this authentication class to mount the process and adapt to your system.

I did not try it any more, I suggest doing something along those lines:

page that requires login.php:

if (!$_SESSION["logado"]) redirecionar_para_login();

login.php

if (loginSucesso()){
    $pattern = "pt.stackoverflow.com";
    //verifica se foi direcionado de alguma outra página sua
    if(preg_match("/$pattern/i", $_SERVER['HTTP_REFERER']){
        redirecionar_paginaAnterior();
    }
    else{
        redirecionar_paginaPrincipal();
    }
}
redirecionar_paginaAnterior(){
    header("Location: " + $_SERVER['HTTP_REFERER']);
    die();
}
