PHP Template Engine built by url

Question

I am searching for a kind of dynamic template engine which I want to built by the url. So if my url is like localhost/root/this/is/the/path/to/signup.php the php code should watch for the file signup.php in the directory this/is/the/path/to/

For this time I am using arrays of the url like the following code shows:

$url = isset($_GET['url']) ? $_GET['url'] : null;
$url = rtrim($url, '/');
$url = explode('/', $url);

if (empty($url[0])) {
    $url[0] = "path/startpage.php";
}

if (isset($url[2])) {
    require "path/error.php";
} else if (isset($url[1])) {

    $file1 = 'path/' .$url[0].'/'.$url[1].'/'.$url[1].'.php';

    if (file_exists($file1)) {
        require $file1;
    } else {
        require "error.php";
    }

} else if (isset($url[0])) {

    $file0 = 'path/'.$url[0].'/'.$url[0].'.php';

    if (file_exists($file0)) {
        require $file0;
    } else {
    require "path/error.php";
    }
}

But with this script I have to do this for every case and this is not so nice. I want to have a solution where the code is looking for the whole url, goes to the directory and require an error or the file, if it exists.

Could you help me please?

The Titon\View library handles this quite easily: https://github.com/titon/View

If an array of paths is passed in for the template, it will generate dynamic lookup paths. https://github.com/titon/View/blob/master/src/Titon/View/View.php#L127

Example:

$view = new Titon\View\View();
$view->addPath('/path/to/views/');
$parsed = $view->run(['path', 'to', 'lookup/folder', 'templateName]);

Can also take a look at the tests to see it in action: https://github.com/titon/View/blob/master/tests/Titon/View/ViewTest.php
