\***************************************************/


// First, set up some variables to serve you in
// getting an email. This includes the email this is
// sent to (yours) and what the subject of this email
// should be. It's a good idea to choose your own
// subject instead of allowing the user to. This will
// help prevent spam filters from snatching this email
// out from under your nose when something unusual is put.

$sendTo = "eric.shomer@gmail.com";
$subject = "Web Site Reply";

// variables are sent to this PHP page through
// the POST method. $_POST is a global associative array
// of variables passed through this method. From that, we
// can get the values sent to this page from Flash and
// assign them to appropriate variables which can be used
// in the PHP mail() function.


// header information not including sendTo and Subject
// these all go in one variable. First, include From:
$headers = "From: " . $_POST["name"] ." ". $_POST["email"] . "<" . $_POST["phone"] .">\r\n";
// next include a replyto
$headers .= "Reply-To: " . $_POST["email"] . "\r\n";
// often email servers won't allow emails to be sent to
// domains other than their own. The return path here will
// often lift that restriction so, for instance, you could send
// email to a hotmail account. (hosting provider settings may vary)
// technically bounced email is supposed to go to the return-path email
$headers .= "Return-path: " . $_POST["email"];

// now we can add the content of the message to a body variable
$message = $_POST["message"];


// once the variables have been defined, they can be included
// in the mail function call which will send you an email
mail($sendTo, $subject, $message, $headers);
