Re: Re: list() limitations

The big question is: how would You (Philip,Yasuo) want list to behave when it encounters a hash? Do you want to get the keys ? Or the values? Or do you want to get the hashed element on its own again as key => value ? 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. 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. Unless someone comes with really intuitive and useable I examples I don't think it should change at all (the list construct). - Markus On Sat, Apr 06, 2002 at 05:01:23PM +0900, Yasuo Ohgaki wrote : > Philip Olson wrote: > >>> $foo = array('a' => 'apple', 'b' => > >>> 'banana'); > >>> > >>> // Notice - Undefined offset: 1 > >>> // Notice - Undefined offset: 0 > >>> list($a,$b) = $foo; > >> > >>Isn't this line should be > >> > >>list($a, $b) = array_keys($foo); > >>or > >>list($a, $b) = array_values($foo); > > > > > >Sure that works. > > > > > >>I might miss you point, since it seems we are > >>going to make these feature requests bogus. > > > > > >Why? list() working with associative arrays > >seems bogus to you?
