I recommend you to start step by step. forget about PHP for now. just focus on the fundamental client-side technologies like CSS, JS, and HTML. just create an HTML file and start coding. when you feel you are ready for the next step start exploring other js libraries like React or Vue etc.. and stick with one of them which suits you the most. finally, explore server-side technologies you may stick with javascript for server-side logic using nodejs or preferring to learn PHP for some reasons.
