PEAR邮件功能 - 换行问题

I'm trying to send a simple text-only email with an attachment. Everything's working great so far aside from line-breaks being properly inserted. Code:

$text = 'Product Name: '.$exchange;
    $text .= '
Company Name: '.$company_name;
    $text .= '
Contact Name: '.$contact_name;
    $text .= '
Contact Email: '.$contact_email;
    $text .= '
Website: '.$website;
    $text .= '
Description: '.$description;


$subject =  "I'm interested in signing up.";

$visitor_email = 'blah@blah.com';

$crlf = "
";

$message = new Mail_mime($crlf);

$message->setTXTBody($text);

$message->addAttachment($path_of_uploaded_file);

$body = $message->get();

$extraheaders = array("From"=>$from, "Subject"=>$subject,"Reply-To"=>$visitor_email);

$headers = $message->headers($extraheaders);

$mail = Mail::factory("mail");

$mail->send('blah@blah.com', $headers, $body);

 if (PEAR::isError($mail)) {
    echo($mail->getMessage());
}
else {
    echo("Your request has been submitted successfully. Thanks!");
    header("Location: home.html");
    die();
}

} else {
  // submitNoLogo();
    echo 'not sent';
}

In the email, all the text is on one line with 's between where I wanted the lines. Anyone know what might be up? Thanks.

put your $text in double quot instead of single

 <?php
     $text = 'Product Name: '.$exchange;
     $text .= "
Company Name: ".$company_name;
     ....

You should put not just /n, also put them on the end not beginning

$text .= 'Company Name: '.$company_name.'
';
$text .= 'Contact Name: '.$contact_name.'
';
$text .= 'Contact Email: '.$contact_email.'
';
$text .= 'Website: '.$website.'
';
$text .= 'Description: '.$description.'
';

are end of line characters for Windows systems and is the end of line character for UNIX systems.
