how i show query result in index.phtml?

回答1:

You need to return a ViewModel to the application with properties set in an associative array, otherwise a default ViewModel will be returned with no properties.

Eg:

return new ViewModel(array(
    'content' => 'foo bar!'
));

Then in your .phtml file:

<p><?php print $this->content; ?></p>
