If you would like to use CodeIgniter's classes from within your own custom classes you can do so as follows: First, assign the CodeIgniter object to a variable: Once you've assigned the object to a variable, you'll use that variable instead of $this: You'll notice that the above get_instance() function is being passed by reference: This is very important. Assigning by reference allows you to use the original CodeIgniter object rather than creating a copy of…
