I want to send a verification mail using php. What is tha code and can i do this using localhost ?

Answer 1

That's why you should use PHPMailer which doesn't require local smtp server.

https://github.com/PHPMailer/PHPMailer

It uses existing smtp servers.

But usually web hotels comes with smtp servers but for localhost this is the easiest way.

Answer 2
