如何更改网站中的许多网页？

I am making website and this website will have more than 20pages. I am using my template to add a webpage. This template has header and footer, so I just add the body of new page. But, what if I want to change navigation bar in the header, then I have to change all 20 pages that I already made to correct. I want to know better way. I read a book, and it says about "php include" function. Should I use this function in the header and footer of each webpage to call header and footer file? If I want to change the navigation bar in the header, all I can do is changing only one header file, then rest of website will be changed.

Is this correct way? In this case, what do you do? I am a beginner, so please advise me. Thank you in advance.

    You should build your website as following. The header.html would contain the navigation.

    header.html

    <!doctype html>
<html>
    <head>
        ...
    </head>
    <body>
        <nav>
           ...
        </nav>

    footer.html

            <footer>
        ...
        </footer>
    </body>
</html>

    page.php

    <?php
   require_once 'header.html';
?>

Your content goes here

<?php
   require_once 'footer.html';
?>

    You should use require_once so the header and footer will be imported only once per script and if the header or footer cant be found, the script will throw an exception and stop the "application".

    "require_once" and "require" are language constructs and not functions. Therefore they should be written without "()" brackets!
