» SSI Includes
Server Side Includes (SSI) are used to create functions, headers, footers, or elements that will be reused on multiple pages.
The tutorial menu on the left of this page is in a SSI include. It appears on every page and to update it we only have to change the one include file and all pages are automatically updated. Imaging we added a new page and had to add a link to every single tutorial page? NUTS!
Server Side Includes
You can insert the content of one file into another file before the server executes it, with the include() function. The require() function is used to create functions, headers, footers, or elements that will be reused on multiple pages.
This can save the developer a considerable amount of time. If all of the pages on your site have a similar header, you can include a single file containing the header into your pages. When the header needs updating, you only update the one page, which is included in all of the pages that use the header.
Example
The following example includes a header that should be used on all pages:
<html> <body> <? include("header.htm"); ?>
<p> Some text </p> <p> Some text </p> </body> </html> |
