A phone book application for companies with a convenient multi-user admin panel that can be run on the local network or the Internet. Codeigniter 3 is completely original using php framework and MySQL. It is a multi-user and administrator-level system. The database structure is located in the text file in the repo and uses the directory name as the database name. However, if you do not delete my name and surname, respecting the copyrights, you can make any edits you want if you specify the source.
You can contact me for similar multi-user (admin panel) web (internet or intranet) projects.
