Online Information System

Your opinion is highly appreciated❤

Hello everyone! Can I ask for your opinion on what languages and courses should I use to create an Online Information System?

Basically, I need to build webpages that displays information with a user and admin login. Admin side should have a dashboard to manage the submitted requirements of users.

For my poor judgment, i am going to take HTML, CSS, JS, PHP, SQL. Is this good to go? Or should I include/exclude something else? Thank you in advance! God Bless!
