Is PHP lying to me?

[NotionCommotion]

How can this be?

$app->get('/1.0/configure', function (Request $request, Response $response, $args) {
    exit((isset($this->db)?'$this->db is set':'$this->db not is set').'<pre>'.print_r($this,1).'</pre>');
    $mapper=new \MyApp\Configure(['logger'=>$this->db]);
    echo('<pre>'.print_r($mapper->display(),1).'</pre>');
    return $this->view->render($response, 'configure.html',$mapper->display());
})->setName('configure');

$this->db is set

The forum software is not being nice to me and the editor is not appearing correctly for the first post.  I think it might be because I included too much text.  What confuses me is when I look at $this, I don't see the immediate property 'db" being set, but it appears to be so.
