mysqli::$insert_id

mysqli_insert_id

(PHP 5, PHP 7, PHP 8)

mysqli::$insert_id -- mysqli_insert_idReturns the value generated for an AUTO_INCREMENT column by the last query

Description

Object-oriented style

int|string $mysqli->insert_id;

Procedural style

mysqli_insert_id(mysqli $mysql): int|string

Returns the ID generated by an INSERT or UPDATE query on a table with a column having the AUTO_INCREMENT attribute. In the case of a multiple-row INSERT statement, it returns the first automatically generated value that was successfully inserted.

Performing an INSERT or UPDATE statement using the LAST_INSERT_ID() MySQL function will also modify the value returned by mysqli_insert_id(). If LAST_INSERT_ID(expr) was used to generate the value of AUTO_INCREMENT, it returns the value of the last expr instead of the generated AUTO_INCREMENT value.

Returns 0 if the previous statement did not change an AUTO_INCREMENT value. mysqli_insert_id() must be called immediately after the statement that generated the value.

Parameters

mysql

Procedural style only: A mysqli object returned by mysqli_connect() or mysqli_init()

Return Values

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.

Only statements issued using the current connection affect the return value. The value is not affected by statements issued using other connections or clients.

Note:

If the number is greater than the maximum int value, it will be returned as a string.

mysqli_query($link$query);

printf("New record has ID %d.\n"mysqli_insert_id($link));
