in reply to Global dbh and inserts
I would recommend that things like last_insert_id be used only immediately after a statement that inserted something, and that the pair of statements be wrapped in an SQL transaction with an appropriate isolation level. This kind of highly-temporal value must not be maintained in any sort of global variable. If you do that, you will create a “random, un-reproducible, yet very fatal” bug of the very, very worst kind.
