1. Convert all the pages that you plan to use the includes on to PHP. There's nothing special that you need to to. Just change the extension on the files to .php.
2. Make two new pages. Title one header.php and the other footer.php. You don't need to name them that, but that's what I'll be using throughout the tutorial. 3. Open one of your pages. Copy everything above the unique content for that page and paste it into the header page. Then replace the part that is now on the header page with the following code. <?include("header.php");?>
4. Now copy and paste everything below the unique content into the footer page. Replace that part on your page with the following code.
<?include("footer.php");?>
You'll need to replace the parts of code on every page that are now on the header and footer pages with the codes I provided. It's a bit tedious, but from now on you'll be able to change every page by simply adjusting what's on the header and footer pages.
