How to make a simple php handler for a feedback form with two fields?

Question

PHP

The site has a form with two fields: name and phone number. We need a simple handler to send the entered data to e-mail.

Answer 1

Receive data via $_POST or $_GET and the mail() function; send data wherever you want

Answer 2

Well, I know this. I would like to understand how to write code. This is so understandable. It is necessary for me through post just. I already did a similar form, with only one field. How about with two?
