public $send_html = FALSE;
private $message = '';
private $headers = '';

public function send($to = NULL,
$subject = NULL,
$message = NULL,
$headers = NULL) {
if (func_num_args() >= 3) {
$this->to = $to;
$this->subject = $subject;
$this->message = $message;
echo $this->to
if ($headers) {
$this->headers = $headers;
}

} else {

if ($this->from) {
$this->headers .= "From: " . $this->from . "\r\n";
}
