I would advise that you learn the basic front-end first a.k.a "Fullstack dev" - that comes wih HTML, CSS and JS (javascript).
Then learn the basic back-end a.k.a. (Server-side dev) - that comes with MySQL [database-this is where you store and pull records/data] and PHP [server scripting, this is responsible processing data i.e. user submits form from front-end]
Then saka ka mag-aral ng "Frameworks" for both front-end and back-end.
For Front-end, study jQuery and Bootstrap - or you can go Angular and Bootstrap.
For Back-end, if PHP aaralin mo, I'd recommend you start with Laravel.
