Little Help?

I've got this mailing script, it's a work in progress, I'm getting  this error:

Parse error: parse error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/xxxx/public_html/mailer2.php on line 55

Line 55 is this: $form .= "<form action=\" $_SERVER['PHP_SELF'] \" method=\"post\">";

Any ideas why?


#assign form values
$name = $_POST['name'];
$mail = $_POST['email'];
$phone = $_POST['telephone'];
$message = $_POST['message'];
$sent = $_POST['submit'];
