mysqli->insert_id -- Returns the auto generated id used in the last query

Description

Procedural style:

mixed mysqli_insert_id ( object link)

Object oriented style (property):

class mysqli {

mixed insert_id

}

The mysqli_insert_id() function returns the ID generated by a query on a table with a column having the AUTO_INCREMENT attribute. If the last query wasn't an INSERT or UPDATE statement or if the modified table does not have a column with the AUTO_INCREMENT attribute, this function will return zero.

Notatka: Performing an INSERT or UPDATE statement using the LAST_INSERT_ID() function will also modify the value returned by the mysqli_insert_id() function.

Zwracane wartości

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.

Notatka: If the number is greater than maximal int value, mysqli_insert_id() will return a string.
