How can I send an email using PHP?

It’s possible using PHP’s mail() function. Remember the mail function will not work on a local server.

<?php
    $to      = '[email protected]';
    $subject = 'the subject';
    $message = 'hello';
    $headers = 'From: [email protected]'       . "\r\n" .
                 'Reply-To: [email protected]' . "\r\n" .
                 'X-Mailer: PHP/' . phpversion();

    mail($to, $subject, $message, $headers);
?>
