# mysqli_insert_id

(PHP 5 CVS only)

mysqli_insert_id

(no version information, might be only in CVS)

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.
