Which row did I just insert?

I created a PHP file to insert a new record into a database. The table's ID field is set to auto increment. Multiple users may be inserting rows simultaneously, so the highest ID is not a good indicator for which row I just inserted. How can I get the ID from the row I just inserted?

Yep, LAST_INSERT_ID().

Yeah but make sure you get via last insert id immediately after doing the insert . . . I always use a new select with the unique data I just inserted to make sure it's the relevant record.

Select id from table where email='inserted@email.com' and user_id=12345;

It's always a **very good idea** to use a second field for user_id or other unique id rather than the auto increment field.
