calling last_insert_id() after INSERT is the number one rule
of course :)
What i mean was, what if the INSERT query fail, but the script still
execute the last_insert_id() function?
Most probably the returned value would be wrong, because it will
return the last_insert_id of previous INSERT query (from previous

I might be wrong, but i think PHP's mysql_insert_id() must be using
MySQL's API function call.
Meaning, it will return whatever value MySQL return.
Or in other word, mysql_insert_id() and last_insert_id() will return
the same result.
I have look thru the manual link above, and i think the phrase
"immediately after" in the manual is more to advise the user to do
mysql_insert_id() immediately after the INSERT query,
because last_insert_id value might get overwritten by the newest one.
the "immediately after" phares in the manual doesn't mean that PHP's
mysql_insert_id() function is somehow tied to the previous/last
INSERT query, so that if the INSERT fails then mysql_insert_id()
will intelegently return the correct value.
just my 1 cent....
