mysqli_insert_id: What if someone inserts another row just before I call this? (2 answers)

Closed 3 years ago.

is it safe to use mysqli_insert_id() when the database is heavily used and more than one id maybe inserted in the same time, or it will get only the id that inserted by a query from this user..

回答1:

mysqli_insert_id() is specific to the database connection , it returns the ID of the row which you inserted most recently.
