cubrid_insert_id — Return the ID generated for the last updated `AUTO_INCREMENT` column

### Description

cubrid_insert_id(resource `$conn_identifier` = ?): string

The cubrid_insert_id() function retrieves the ID generated for the AUTO_INCREMENT column which is updated by the previous INSERT query. It returns 0 if the previous query does not generate new rows, or FALSE on failure.

> Note: CUBRID supports AUTO_INCREMENT for more than one columns in a table. In most cases, there will be a single AUTO_INCREMENT column in a table. If there are multiple AUTO_INCREMENT columns, this function should not be used even if it will return a value.

### Parameters

`conn_identifier`
  The connection identifier previously obtained by a call to cubrid_connect().

### Return Values

A string representing the ID generated for an AUTO_INCREMENT column by the previous query, on success.

0, if the previous query does not generate new rows.

`false` on failure.

### Changelog

Version | Description
--- | ---
8.4.0 | Change the return value from an array to string; Remove the first parameter class_name.

### Examples

Example #1 cubrid_insert_id() example

`<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
@cubrid_execute($conn, "DROP TABLE cubrid_test");
cubrid_execute($conn, "CREATE TABLE cubrid_test (d int AUTO_INCREMENT(1, 2), t varchar)");
for ($i = 0; $i < 10; $i++) {
cubrid_execute($conn, "INSERT INTO cubrid_test(t) VALUES('cubrid_test')");
}
$id = cubrid_insert_id();
var_dump($id);
cubrid_disconnect($conn);
?>`

The above example will output:

    string(2) "19"
