In this case there is no need to use a multidimensional array, as
PHP's arrays are maps, which has many purposes.
For the above, you might as well use:
$a = array(
'Name' => $name),
'Message' => $msg),
'Subject' => $subj)
);

You can say that. An important note is that "list" should be used only
when the array is sequently indexed like an ordinary array or vector.
Each "argument"(variable) passed to "list" will given the value of
respectively the 1st(indexed zero), 2nd, 3rd and so forth, value in
the array.
I.e. given the array:
$arr = array('a', 'b', 'c', 7 => 'd');
This:
list($a, $b, $c) = $arr;
is equivalent to:
$a = $arr[0];
$b = $arr[1];
$c = $arr[2];
This:
list($a, $b, $c, $d) = $arr;
will give a warning for undefined index, because there is no $arr[3].
