Ok, these results are obvious, IMHO.

But these two are not. For the first case: Where in the manual does it
state that "$arr[key]" should be evaluated like $arr["key"]? For the
second: Within double quotes variables should be evaluated, so why
doesn't $arr['key'] evaluate to foo?

Jep, these are obvious, too.
