Hello

Your template engine seems to work perfectly!

This rendering is made running:

    $output = $template_engine->render(
        'hello.htm',    // this is the view file name
        array(          // these are the parameters passed to the view file
                        // as PHP variables
            'name' => isset($_GET['name']) ? $_GET['name'] : 'Anonymous'
        )
    )
    // which means that, in your view file, you can write:
    echo $name

To test it, add a "name" variable to your current URI, for instance name=Myname ...

In a view file, $_template is the whole template engine and is array-accessible:

    $_template['web_root_path']
    // will be rewritten as 
    $_template->getWebRootPath()
    // and will be searched in the "view" or "template" objects
    $_template->template->getWebRootPath()
    $_template->view->getWebRootPath()
    
    // in this case:
    $_template['web_root_path'] = $_template->template->getWebRootPath()
        => ""    

See the documentation for a full PHP objects review.
