How to Get Last inserted ID in CodeIgnier?

We often need last inserted ID for different reasons(for example when you need to store foreign key), Immediately after a record has been inserted into the database, you can get the id that was auto incremented(primary Key).

Basic PHP MySQL Method

<?php 
mysql_insert_id();
?>

simply call CodeIgniter method

<?php
$this->db->insert_id();?> 
?>

That’s it!
