Use PHP to create a static website template framework (4) static website template framework

First, we will write a template file for all the common page elements and the overall layout of the page as before. then, we will delete the public part from all the pages, leaving only the page content; next, add three lines of PHP code to each page, as shown below:







Hi!

Welcome

This method basically solves the various problems mentioned above. Currently, there are only three lines of PHP code in the file, and no line of code is directly related to the template. Therefore, there is little possibility to modify the code. In addition, because the HTML content is outside the PHP tag, there is no special character processing problem. 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 required PHP code related to the template. The pageStart function sets the template object and page title. the pageFinish function parses the template and generates the result and sends it to the browser.

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


Require ('class. FastTemplate. php ');

Function pageStart ($ title = ''){
GLOBAL $ tpl;
$ Tpl = new FastTemplate ('.');
$ Tpl-> define (array ('main' => 'main.htm ',
'Head' => '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 ');
}
