I will write a website, after submitting the form on the website, store the relevant information about the form in the back-end database, and then reorganize the home page of the website. Read the content from the database to change the content of the home page (for example: add a card, the content is read from the database), what tools should be used in this process? As far as I know, I need to learn php+MySQL, first, so what tools should be used to automatically add those contents in the front-end web page? Can the same be done by PHP?
