A PHP Mail Class

Below is a Mail class I created in PHP, it requires 4 arguments on initiation of the class via the constructor and uses the method ->send() to send the created mail once complete.

class Mail {
var $to;
var $subject;
var $content;
var $headers;

function Mail($to, $subject, $content, $from){

$this->to = $to;
$this->subject = $subject;
$this->content = $content;
$this->headers = "Content-type: text/html; charset=iso-8859-1\r\nFrom: $from";

$this->content = "".$content."";

function send(){
return mail($this->to, $this->subject, stripslashes($this->content), $this->headers);
