Add backend config to hosted app

Hi All, I am self studying web app development so pardon for newbie questions. I have just completed learning PHP / MySql.
My question is, If I have a tiny fullstack app (HTML/CSS/PHP/MySql) , which I have setup locally using XAMPP (incl. tables and local connection string). If I want to deploy this on Netlify and make the web app use mySQL tables and data (or any other way) , how can I achieve this? Basically i would like the web app to be functional with its CRUD behavior. I dont own a domain too.
I hope I could make myself understood. Thank you all.

Hi, @prat1800. Running PHP after deployment isn’t possible at Netlify. We have a support guide with more details here:
