The statement is confusing at best.  For the casual user auto_increment
is the way to do.  I say for the casual user.  That is typical me and
you.  Basically if you do an insert a unique value is inserted at the
time of the insert.  As mentioned, there are ways to get this value back
in the return.  

Now why I say it's for the casual user is because if you are using
triggers then you can do things prior to this value being used and then
the statement above is correct.  But you are not going to be using

So, put an auto_increment on the key field and find one of the 2^16
samples of how this works with PHP.
