What's the practical way to load header and footer

[eluser]EEssam[/eluser]
Hello,

I'm wondering what is the most practical way to load a header and a footer.

I know I can do:

$this->load->view('header');
$this->load->view('myview');
$this->load->view('footer');

But I just don't see how I should call this in almost each function in my controller classes.

Please advise.
