PHP Contact form won't work - php

Question

I've tried every php contact form tutorial but I can't get any of them to send the email properly. They all just show the code but don't send the email. This is the HTML code I have right now:
<form method="POST" action="scripts/contact.php">
<input id="name" name="name" placeholder="Name*" type="text" /> <br>
<input id="subject" name="subject" placeholder="Subject" type="text" /> <br>
<input id="email_address" name="email" placeholder="Email address*" type="text" /> <br>
<textarea id="message" name="message" placeholder="Your message*"></textarea>
<input id="submit" type="submit" name="submit" value="Send" />
</form>
and this is the php I have:
<?php
$name = $_POST['name'];
$subject = $_POST['subject'];
$email = $_POST['email'];
$message = $_POST['message'];
$to = "benmuschol#gmail.com";
$subject = "Hello World";
$message = "Name: $name \n Subject: $subject \n Email: $email \n Message: $message \n";
$headers = "From: $email" . $email;
mail($name,$email,$subject,$message,$headers);
echo "Mail Sent.";
?>
I have decent knowledge of HTMl but next to none of PHP. Any help would be greatly appreciated.

Answer 2

use following php code:
<?php
$name = $_POST['name'];
$subject = $_POST['subject'];
$email = $_POST['email'];
$message = $_POST['message'];
$to = "benmuschol#gmail.com";
$subject = "Hello World";
$message = "Name: $name \n Subject: $subject \n Email: $email \n Message: $message \n";
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
// Additional headers
$headers .= 'From: '.$email. "\r\n";
if(mail($to, $subject, $message, $headers))
{
echo "Mail Sent Successfully.";
}
else
{
echo "Error in Mail Sent.";
}
?>
