Template framework for making static Web sites in PHP (iv)

Template framework for static web sites

First, we write the template file for all the common elements of the page and the overall layout of the page as before, then delete the public section from all the pages, leaving only the page content, and then add three lines of PHP code to each page, as follows:

Welcome to visit

?>

This approach basically solves the various problems mentioned earlier. Now there are only three lines of PHP code in the file, and no line of code directly touches the template, so it is very unlikely to change the code. In addition, because the HTML content is outside the PHP tag, there is no processing problem with special characters. We can easily add these three lines of PHP code to all static HTML pages.

The Require function introduces a PHP file that contains all the necessary PHP code related to the template. Where the Pagestart function sets the template object as well as the page title, the Pagefinish function resolves the template and generates the result to send to the browser.

How is this implemented? Why is the HTML in the file not sent to the browser before calling the Pagefinish function? The answer lies in a new PHP 4 feature that allows the content of the output to the browser to be intercepted into the buffer. Let's take a look at the specific code for prepend.php:


Require (' class. Fasttemplate.php ');

function Pagestart ($title = ") {
GLOBAL $tpl;
$TPL = new Fasttemplate ('. ');
$TPL->define (' main ' = ' main.htm ',
' Header ' = ' header.htm ',
' LeftNav ' = ' leftnav.htm ');
$tpl->assign (' TITLE ', $title);
Ob_start ();
}

function Pagefinish () {
GLOBAL $tpl;
$content = Ob_get_contents ();
Ob_end_clean ();
$tpl->assign (' CONTENT ', $content);
$tpl->parse (' header ', ' header ');
$tpl->parse (' LeftNav ', ' leftnav ');
$TPL->parse (' main ', ' main ');
$tpl->fastprint (' MAIN ');
}

?>
