PHP Mail HTML Comment Form Variables - php

Question

Can you provide the proper syntax to pass the html form variables to php mailer?
The php is:
$comment = $_POST['comment'];
$email = $_POST['email'];
$to = 'sssff#gmail.com';
$subject = 'From Website';
$message = $comment;
$headers = 'From: $email';
mail($to, $subject, $message, $headers);
$message needs to contain the contents of $comment
$headers needs to display the contents of $email as return address
Can anyone help me with the proper syntax? Thank you
EDIT
To clarify, the email i receive from the php mailer does not contain the from address contained by $email, nor does the message contain the comments from $comment.
The email is sent fine, but does not contain those crucial elements.
If you'd like to look at the form it is:
<form class="cmxform" id="commentForm" method="POST" action="">
<label for="cname">Name</label>
<input id="cname" type="text" name="name" size="60" class="required" minlength="2" />
<label for="cemail">E-Mail</label>
<input id="cemail" type="text" name="email" size="60" class="required email" />
<label for="curl">URL</label>
<input id="curl" type="text" name="url" size="60" class="url" value="" />
<label for="ccomment">Your comment</label>
<textarea id="ccomment" type="text" name="comment" cols="72" rows="8" class="required"></textarea>
<div id="button2"><input class="submit" id="submit_btn" type="submit" value="Send Email"/></div>
</form>
Thank you for your help

Answer 1

$headers = 'From: $email';
^--- ^---
should be " instead. Single quoted strings do not interpolate variables, so you're using a literal $email as your From address, not someone#example.com.

Answer 2

$comment = $_POST['comment'];
$email = $_POST['email'];
$to = "$email";
$from = 'sender email';
$subject = 'message subject';
//Begin HTML Email Message
$message = "$comment";
//end of message
$headers = "From: $from\r\n";
$headers .= "Content-type: text\r\n";
mail($to, $subject, $message, $headers);
