Question

in the getting started tour of Symfony2 i came across this:

    {# array('user' => array('name' => 'Fabien')) #}
{{ user.name }}

{# force array lookup #}
{{ user['name'] }}

{# array('user' => new User('Fabien')) #}
{{ user.name }}
{{ user.getName }}

{# force method name lookup #}
{{ user.name() }}
{{ user.getName() }}

Can someone explain me the difference?

In twig when you just use foo.bar, foo may be an array (in this case twig expects a key bar), or an object, whereas it expects either a accessible property bar, a methods getBar(), and I guess something I forgot. However, the point is, that twig tries to resolve the kind of access itself and you can throw in, whatever you like (beside that it must obviously in a form of structured data). If you use a specific access method, you take the ability to guess from twig: When you call foo.bar() it’s obviously a method. (Must say, that I never heard of “forced lookup” :X)
