How to retrieve all Variables from a Twig Template?

Question

Is it possible to retrieve all variables inside a Twig template with PHP?

Example someTemplate.twig.php:

Hello {{ name }}, 
your new email is {{ ema

After using duncan's answer for quite some time I finally found the "right" way to dump all twig variables of a template:

{% dump %}

That's it. All the variables available in the template will be dumped and in the dump section of the profiler, not in the middle of your html like with {{ dump() }}.

if you put the contents of dump() into a variable:

{% set d = dump() %}

you 'll get all the variables but in "dump ready" html so it would be a pain to parse it.

Hope that helps.
