Pequeno sistema de templates para PHP5

Falta uma explicação do código e mais algumas informações sobre as funções

class Template {
	private $template;
	private $buffer = array();
 
	function __construct($template, $items){
		$this->template = $template;
		foreach($items as $k => $v) $this->buffer[(is_numeric($k) ? $v : $k)] = (is_numeric($k) ? '' : $v);
	}
 
	public function change($k, $v){
		$this->buffer[$k] = $v;
	}
	public function add($k, $v){
		$this->buffer[$k] .= $v;
	}
 
	public function generate(&$destiny = ''){
		foreach($this->buffer as $k => $v)
			$this->template = str_replace('<!-- '.$k.' -->', $v, $this->template);
		return ($destiny = $this->template);
	}
}

Como usar

<?php
include "lib/template_class.php";
$x = new Template(file_get_contents("index-blank.html"), array('head', 'head title', 'software name', 'software quick info', 'software navigation links'));
 
$x->change('head', '<script>alert("woot!");</script>');
$x->change('software name', 'lulzware');
$x->change('software quick info', 'oi?');
echo $x->generate();
