Access Codeigniter functions from external script
===

So, here's my situation :

- I have a complete app set up with CodeIgniter.
- I'm initiating a **background task**, running a PHP script.

My question :

- How could I use CodeIgniter function (e.g. `$this->db` or `$CI->db` - doesn't matter) from that external PHP script?

*Idea :* Could a workaround, like `include 'index.php';` at the top of the script do the trick?
