I have an HTML file that has a rather long navigation menu inside of it. I want to take that menu out of the HTML and place it into an external PHP page and then call it with
<?php include 'navigation.php'; ?>
in the HTML file.
I have tried just adding this into the HTML file but it doesn't display anything as well as no errors on the page.
What do I need to do (if it's even possible) to keep the files HTML and use the php require function?
