    It should be noted that using mysqli_stmt->insert_id will not result in a unique ID being returned for each execution of a prepared insert statement. In practice, it appears that the first insertion ID is returned. If you are performing multiple inserts with the same prepared statement (one invocation of mysqli_stmt::prepare and multiple invocations of mysqli_stmt::execute() for a given statement), and need to keep the unique ID for each insert, use mysqli_connection->insert_id.

    for those with zerofilled IDs beware as mysqli_stmt::$insert_id will return an integer. In other words, if the ID returned from your query was #000099, the value produced by mysqli_stmt::$insert_id is now #99.

    I have not found a way to fix this beside using sprintf('%06d',$id) but this assumes you know in advance the size of the ID beforehand.
