array problem

[jinwan]

hello,
i have 2 arrays.one is a 1 dimentianal array and the other one is a 2 dimentional array,just name it A and B.

A contain a list of IDs which is the same with the IDs in B.
How can i link A and B togather using the ID so that i can access the other information inside B?i don't mean to merge the arrays.

Well, you could use a[$id] as a key for b:

$key = $a[$id];
echo $b[$key];
