Updating mysql table with values

[old newbie]

I am stuck with a problem.

Have a shopping cart, once the client selects the products, from a SQL table (1), they are taken up by an array variable

A session array variable delivers values using foreach loop.

The php shows all the values sequentially

But the SQL table (2) gets updated with only the last value.

Understand that this will happen due to looping.

So how to go about resolving this

As it loop through each item with php it should also save that single item to the database. The database should have a unique id that increments on every creation of new record.
