Securing a php mail form with variables sent from flash form

[Stand Still]

Hey Guys, I am totally oblivious to php stuff, but I know I need some security on the forms I use. What I do is make my forms in flash and send the variables to a php file that in turn sends them to a specified email...pretty simple. So, below is the php script and if someone could show me how to place some security either in that script or how to point it to some or whatever is easiest and safe... oh, I'd be ecstatic!

 

<?php

 

$name = $HTTP_POST_VARS['Name'];

$email = $HTTP_POST_VARS['Email'];

$phone = $HTTP_POST_VARS['Phone'];

$address = $HTTP_POST_VARS['Address'];

$county = $HTTP_POST_VARS['County'];

$message = $HTTP_POST_VARS['Message'];

 

$message = stripslashes($message);

 

$sendTo = "me@gmail.com";

$subject = "Some Contact Information!";

 

$msg_body = "Name: $name\n";

$msg_body .= "E-Mail: $email\n";

$msg_body .= "Phone: $phone\n";

$msg_body .= "Address: $address\n";

$msg_body .= "County: $county\n";

$msg_body .= "Message: $message\n";

 

$header_info = "From: ".$name." <".$email.">";

 

mail($sendTo, $subject, $msg_body, $header_info);

 

?>

 

Remember, I'm new to all this and need the "Blind Dog" instructions (meaning explain it so a blind dog could do it). Thanks so much.
