code analysis - davy_yg - 08-06-2016

Hello,

I am learning CI code tutorial that I do not understand.  Can anyone help me understand this CI code?


PHP Code:
$data $this->fetch_data_from_db($update_id); 




Where this code comes from : fetch_data_from_db( ) ?

I search the user guide: http://www.codeigniter.com/user_guide/  and do not find the codes.

Another one:

PHP Code:
$data['query'] = $this->_custom_query($mysql_query); 


Where this code comes from : _custom_query(); ?

I search the user guide: http://www.codeigniter.com/user_guide/  and do not find the codes.
