array filling problem

[coccer]

Hy everyone!
I have a problem, with array filling:
I have two arrays and I would like to do something like this:

$months=array("", "January", "February", "etc");

$list[] = array ("key1" => "12", "key2" => $months[$list['key1']]);

so I would like get $list['key2']=december.

thanks for the ideas!

We probably need a better explanation of why you cannot simply do:

$months=array(1 => "January", "February", "etc");
$list[] = array ("key1" => "12", "key2" => $months[12]);
