Is there a way to access partial parameters in code tab?

If i reference partial like this: {% partial 'foo' bar={baz: 'qux'} %}

How I'm supposed to get 'baz' value so i can do something with it in php?

Sorry for a lame question, but I'm kind of a newbie here.

Check this out https://octobercms.com/docs/cms/partials#variables

@Daniel81 Thanks, I've seen the docs. I know how to create variable in php and then use it in partial. What I want do do is other way round: take partial parameter value and use it in php.
