<?php

class Template {

    var $vars;

    function set($key, $value) {
        $this->vars[$key] = $value;
    }

    function parse($file) {
        extract($this->vars);
        ob_start();
        include $file;
        $contents = ob_get_contents();
        ob_end_clean();
        return $contents;
    }
}
?>

Now you can write temaplates like this..
----------------------------------------

Hello my name is $name!

----------------------------------------

And do something like

$template->set('name', 'erisco');
$template->parse('mytemplatefile.php');
