Well, here's some code with some commentary to perhaps help:

Unless the user has a lot of baskets, I would assume you would just list
all the baskets the user has as links on the web page or as a pop up
menu. The value passed by the links or pop up would be the element
number of the array item containing the desired basket.
To extract a basket by name I
If you are looking for something as simple as an index or key rename
function it can be done and without making any copies of the array or
object etc by:
$array['new_key_name'] = $array['old_key_name'];
unset($array['old_key_name'];
The first line creates a reference to the array.

That was it, indeed, but

think these surfers will just see their baskets in different order after
a rename :-)
Of course, if you display the baskets in alpha order by name, it won't
be too much of a shock to them when they are displayed in a

My first question back would be why you create on array with keys you
know you want to change, or why in that case it became necessary to
dereference the original key.
$a['tmp'] = $a['t']; // exact same values by reference (no copy)
Only other way I can think of at the moment is to create a

How do I change the key in an array without having a duplicate
key=$value?
You could maybe use array_flip, change the value, then array_flip again.
Or create your new key=value and unset() the old one.
$array[$new_key] = $array[$old_key];
unset($array[$old_key]);
