我的MVC PHP应用程序在哪里放置这个构建函数？

Question

I'm trying to convert my PHP app into more of an MVC app. I don't have much experience with MVC and I don't fully understand some of/all of the concepts or how to do it with PHP, so I need some help understanding where a particular function goes.

This function returns some HTML depending on if the user is logged in.

public function buildLoggedInMessage() {
    if ($this->User->isLoggedIn()) {
        return ' You are logged in as <strong>'.$this->User->getUsername().'</strong> (<a href="/logout.php">logout</a>)';
    } else {
        return ' <a href="/login.php">Login</a>';
    }
}

My initial thought was to place this function in my "controller" because it asks the User model if they are logged in (which checks the database record), however it "builds" some HTML, so maybe it should be in the view. Should I move it?

I will eventually move the HTML from the function into a template, so ignore the inline HTML.

Would the function be more suitable in the view if it was like this:

public function buildLoggedInMessage() {
    if ($this->Controller->isLoggedIn()) {
        return ' You are logged in as <strong>'.$this->User->getUsername().'</strong> (<a href="/logout.php">logout</a>)';
    } else {
        return ' <a href="/login.php">Login</a>';
    }
}

and the controller asks the model if the user is logged in?

Thanks.

put this function in the controller from where you are calling a login function after if a user authenticated then it will set the session or flash data i.e $this->session->set_flashdata('success', 'you are loged in as $username'); else redirect('login');
