PHP: how to send email basics

Question

I\'m would like to use PHP to send email from my localhost to other people. What do I need to do that?

For example do I need to install mailserver? If I\'m not mistaken

Answer 1

mail("recipient@domain.com", "Subject", "This is an email!");

You just need to install some email server. If you are on linux, you can try exim, if you are on windows, you can use the SMTP server that comes with IIS.
