How to Update Multiple Web Pages Using PHP
PHP can be used to create common content in multiple pages in much the same way as the SSI Virtual Include.
- Server-side is safer than client-side (it doesn't rely on any browser settings).
- Updates are very fast and easy.
- Slight performance overhead at the server end (every PHP page needs to be processed by the server before it is served to the user).
- You usually need to use a special extension for web pages, e.g. .php.
- The server must support PHP (most servers do).
Create a plain text document for the common content and save it in a folder which is accessible from your whole website. You may want to make a special folder for this type of file, e.g. /includes/. Your file might look like this (we'll call this file copyright.html):
<!-- Begin Copyright -->
<span style='color:blue;'>© Copyright MyName 2004</span>
<!-- End Copyright -->
In each page, add the following code:
<?php require("/includes/copyright.html"); ?>
