My opinion is: $foo = array('a' => 'apple', 'b' => 'banana'); list($a,$b) = $foo; print $a; // apple print $b; // banana This would be consistant with how list works with numerical arrays. It gets the values, not the keys. > No, I don't think it's a good idea. That is why we have > array_(keys|values), it makes the code readable and it's easy > to understand. This is understandable but list() works on values, it does this for one type of array but not another. > For me, it would make most sense to have the following: > > list($a, $b) = array('a' => 'apple', b => 'beer'); > > var_dump($a); > array(1) { > ["a"]=> > string(5) "apple" > } > > I don't think many would share _this_ behaviour. > > All in all I think this would get too ambiguous if we would > change the behaviour.

Aside from saying it works on values for numerical arrays I can't say much else. That is intuitive and consistant to me, not ambiguous. Regards, Philip
