Question

How does Stackoverflow reuse their code, especially the header and footer?

So, basically when i click on ‘Tags’ only the content changes, not the header and footer.
What are the best pratises? A link to a simple tutorial would be good.

I’m using HTML5, PHP, and MySQL. No javascript involved yet.

Answer 1

With no framework whatsoever involved, try something along these lines:

<?php

include('header.php');

// do something, render page specific content ...

include('footer.php');
