An array is a "multi-value field". The standard way to do that in SQL is with a dependent table, something like this:
foo(fid, field_a, field_b, field_c); foo_d(fid, value); Or possibly: food_d(fid, delta, value); where delta is essentially an array offset if you want to maintain ordering. I don't know of a clean way to then load that data in all one query. Each dependent table then becomes another simple query, and you link the data up in a PHP data structure of some sort. Modifying the "array" can then get expensive as well. If you don't have a delta, then a delete/insert cycle to change the values is generally the easiest solution. If you do have a delta, then you may be able to individually identify and delete/update values in the "array" by fid and delta as the primary key.
