Well, whatever you ask for is given to you in order. So array_keys() and
array_values() give you things that way. The loops will let you specify whether
you want pairs or just values, so you can say foreach($arr as $key=>$val){}or
just foreach($arr as $val) (I don't like the "as" syntax either). Similarly for
while: while(list($key, $val) = each($arr){} or just while(list(,$val) =
each($array){}. each() by itself actually gives you this:

Array
(
    [1] => b
    [value] => b
    [0] => a
    [key] => a
)

Which I never knew before. So list() looks at the numeric indices.
