codeigniter clean code

in this tutorial i share my way to practice SEO in codeigniter projects and how i generate clean URLs 

hope to enjoy learning 

codeigniter clean code

Replace only spaces ? No accents? No diacritics ? I'm doing something like this: url_title(convert_accented_characters($data['title']), '-', true)

in most tutorials i post simple code as possible for beginners to explain my thoughts and if someone need more there is more
but i am happy with your replay and i will update code

thanks for sharing

find by slug slow more than id. So I don't like it. In my opinion, the url should be domain.com/this-is-slug-21 (21 is ID )
