coding autoresponder into phpmail - php

Question

I've tried a few people's answer, none worked. I have a good working phpmail function, I just want to add an autorespond function to it, so that the sender can be immediately notified that submission was received.
My code is this:
<?php
$mail_to_send_to = "contact#matejkadesign.com";
$your_feedbackmail = "form#matejkadesign.com";
$sendflag = $_REQUEST['sendflag'];
if ( $sendflag == "send" )
{
$name = $_REQUEST['name'] ;
$email = $_REQUEST['email'] ;
$message = $_REQUEST['message'] ;
$headers = "From: $your_feedbackmail" . "\r\n" . "Reply-To: $name <$email>" . "\r\n" ;
$a = mail( $mail_to_send_to, "Contact request", $message, $headers );
if ($a)
{
print("Message sent, thank you! You can send another");
} else {
print("Message wasn't sent, please check that your email was filled in properly");
}
}
?>
I want to say something like this in the autorespond:
Thank you for contacting us. This is an automatically generated reply confirming your submission. We will get back to you as soon as possible.
Sincerely,
John Doe

It is not clearly what you want but I doing a wild guess. You want to e-mail the user when he/she used this form. Use this code:
<?php
$mail_to_send_to = "contact#matejkadesign.com";
$your_feedbackmail = "form#matejkadesign.com";
$sendflag = $_REQUEST['sendflag'];
if ( $sendflag == "send" ) {
$name = $_REQUEST['name'] ;
$email = $_REQUEST['email'] ;
$message = $_REQUEST['message'] ;
$headers = "From: $your_feedbackmail" . "\r\n" . "Reply-To: $name <$email>" . "\r\n" ;
$a = mail( $mail_to_send_to, "Contact request", $message, $headers );
if ($a)
{
print("Message sent, thank you! You can send another");
$message_back = "Thank you for contacting us. This is an automatically generated reply confirming your submission. We will get back to you as soon as possible.";
mail( $email, "Contact request", $message_back, $headers );
} else {
print("Message wasn't sent, please check that your email was filled in properly");
}
}
?>
