I am sorry if this is a repeating question, but I can't find anyone who might have the same question as me yet. I am new in html and php, and I am trying to learn more by practising, basically creating a registration form and keep all the data in the MySQL database, by using xampp. I have created a registration form and saved it as a .html file format, but how can I use php to send the user input from html to the MySQL database? I have seen a lot of examples on Google, but most of them are using php file format, for example instead of registration.html, they use registration.php. I really do appreciate your help. Thank you very much StackOverflow community members.
P/S: I use Visual Studio Code to do this
