The mysqli_insert_id() function returns the ID generated by a query (usually INSERT) on a table with a column having the AUTO_INCREMENT attribute. If no INSERT or UPDATE statements were sent via this connection, or if the modified table does not have a column with the AUTO_INCREMENT attribute, this function will return zero.
Bilginize:
Performing an INSERT or UPDATE statement using the LAST_INSERT_ID() function will also modify the value returned by the mysqli_insert_id() function.

The value of the AUTO_INCREMENT field that was updated by the previous query. Returns zero if there was no previous query on the connection or if the query did not update an AUTO_INCREMENT value.
Bilginize:
If the number is greater than maximal int value, mysqli_insert_id() will return a string.
