mail headers and arrays

[Anon]

I am in the process of building a mailing list app which takes a text file that the user has uploaded and sends it out to a mailing stored in a database. I'm trying to make the subject equal the fifth line of the text file. I have grabbed the text file and put it in to an array like so:
<?
$filearray=file("$directory", "r");
$num = count($filearray);
$message="";
for($i=0; $i<$num; $i++)
$message .= "$filearray[$i]\n"; ?>

I then send out the the message to the mailing list like so:

<?
$email = (list of addresses from database)
$subject = $filearray[4];
$headers="";
$headers .= "From: ACPD<[e-mail]> \n";
$headers .= "X-Mailer: PHP\n"; $headers .= "X-Sender: <[e-mail]>\n";
$headers .= "X-Priority: 1\n";
$headers .= "Return-Path: ACPD<[e-mail]>\n";

mail($email, $subject, $message, $headers)
?>

It seems that when I set the $subject variable equal to the array filearray[] which holds the mesage it screws up all my headers and the message arrives with the wrong header info, but when I set the variable $subject to just a string it works fine. Does anyone know why this is happenning? Am I missing something?

I think the problem is with the newline character that is still attached to the string. The file() function leaves the newline character attached to the line. Try removing it from $filearray[4] before you set it as the subject.
