What is PHP web mailer and SMTP?

Answer 1

SMTP stands for Simple Mail Transfer Protocol. PHP has a built-in function called mail() that takes 5 arguments. TO, Subject, Message, Headers, Additional Parameters. Hostmysite.com has some examples in their support section but below is another example. Here is the syntax you will need to use:

<?php

$to = 'nobody@example.com';

$subject = 'the subject';

$message = 'hello';

$headers = 'From: webmaster@example.com' . "\r\n" . 'Reply-To: webmaster@example.com' . "\r\n" . 'X-Mailer: PHP/' . phpversion();

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

?>
