CodeIgniter URLs
URLs in CodeIgniter are designed to be search-engine and human-friendly. Rather than using the standard “query-string” approach to URLs that is synonymous with dynamic systems, CodeIgniter uses a segment-based approach:
URL : gophp.in/news/article/my_article
URL Structure: gophp.in/class/method/ID
Here news is the name of the Controller
article is the method available in a news class
my_article is the parameter to the article method
An URL is the combination of Base URL and Base URI
URL :https://gophp.in/news/article/my_article
Base Url: https://gophp.in
Base URI: /news/article/my_article
