CodeIgniter For Project : Lesson 105 - Helper and Library
1 like473 views
The document discusses helpers and libraries in CodeIgniter. Helpers are collections of functions that help with tasks, and are loaded with $this->load->helper. Common helpers include url for URLs and form for forms. Libraries provide specific functionality and are loaded with $this->load->library. Common libraries include session for managing sessions, input for retrieving input, and form_validation for validating forms. Both helpers and libraries are loaded and used via CodeIgniter's loader methods.
