Mail

mail() is the PHP native function that sends emails. It is a relay to system commands that actually send the mail.

mail() does not provide support to structure mail, in particular attachements. This is left to custom components, such as PHPMailer.

<?php

    $message = World;

    mail('contact@php.net', 'Hello!', $message);

?>
