Hello again,
This is a very lightweight and very easy to use template class for PHP5. Supports sub templates using a nice little magical method.  Template Class PHP Code: <?php
/**
* Basic template engine for PHP5. Not bloated
* and just gets the job done.
*
* @package Template
* @author David Parr <dave@snezo.com>
* @copyright Copyright (c) David Parr, 2008
*/
class Template
{
// Template name
protected $name;
// Local and global data. Gl
protected $data = array();
/**
* Constructor sets the template name, and makes sure
* it exists.
*
* @param string The template name
*/
public function __construct($name)
{
if( ! is_file(TEMPLATE_PATH . $name . TEMPLATE_EXT))
die('Invalid template: ' . $name);
$this->name = $name;
}
/**
* Magically set some template data.
*
* @param string Key of the data
* @param string Value of the data
*/
public function __set($key, $value)
{
$this->data[$key] = $value;
}
/**
* Magically render a template. Great for sub templates.
*
* @return string
*/
public function __toString()
{
// Need the new line character to format output correctly :)
return $this->render() . "\n";
}
/**
* Renders a template.
*
* @param bool Should the template be directly printed out?
* @return string
*/
public function render($print = FALSE)
{
// Begin output buffering
ob_start();
// Extract data to local namespace. Don't worry extract isn't great
// but this is only in local scope so nothing to worry about :)
extract($this->data, EXTR_SKIP);
// We do it like this so we can use the direct name of the variable
// rather than having $this everywhere in your templates
require_once(TEMPLATE_PATH . $this->name . TEMPLATE_EXT);
$output = ob_get_clean();
if($print === TRUE)
{
echo $output;
return true;
}
return $output;
}
}
?> Example PHP Code: <?php
require_once('classes/Template.php');
// Template path with a trailing slash and extension of template files with a dot prefix.
// This lets you decide where to place your templates and what extension to give them i.e. '.template.php', '.tpl.php'
// or whatever suits your needs.
define('TEMPLATE_PATH', dirname(__FILE__) . '/templates/');
define('TEMPLATE_EXT', '.php');
// Create a home template, with header and footer as sub templates
$home = new Template('home');
$home->message = 'Hello world';
$home->header = new Template('header');
// This is how you set a variable in a sub template. Easy as pie :)
$home->header->title = 'Home Page';
$home->footer = new Template('footer');
$home->render(TRUE);
?> Header PHP Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title><?php echo $title; ?></title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
Home PHP Code: <?php echo $header; ?>
<h1><?php echo $message; ?></h1>
<?php echo $footer; ?> Footer All the above will produce.. Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<h1>Hello world</h1>
</body>
</html>
Thanks and enjoy!
