The left table is the table to the left of the join. So:

SELECT id FROM table1 LEFT JOIN table2...

table1 is the left table and table2 is the right table (if you were to
use a RIGHT JOIN).

UPDATEs and INSERTs follow the same procedure.

When you INSERT an entry into the main table, you then use the function
mysql_insert_id() which will give you the value of the last 'id' column
generated, which you can then use to insert data into the secondary
tables.

If you are using MySQL 4.1 or later you should use the mysqli extension
and not the older mysql one. UNLESS you are relying on the older style
passwords, which is a BAD idea.
