Answer 1

Welcome to the Backend side. You need to transfer data to PHP script, this script connects to your RDBMS, initializes the needed databases and tables if needed and puts given data into tables in specific order (preset by you).

HTML by himself can't store data. PHP can create files and open them later, but it's not so effective. RDBMS were created for keeping data.
