This must be a function or trigger to break one statement into two. You
could of course simply use two separate statements in PHP as long as
they are in the same transaction. If you're going to perform this
action in two steps then putting both in a function or trigger is often
preferable.

I wonder
Maybe to show how found works and how to ignore errors - that is my
assumption only.

SAVEPOINT foo;
INSERT INTO table (col1,col2,col3) VALUES

Yes it is.
You can implement trigger on table to check if inserted record is new.
Still it is on DB side.
I don't know PHP well enough but I think You can call function e.g. SELECT
myschema.InsertWhenNew (val1, val2, val3); in the same way as You
call INSERTS
