PHP:iCal创建，如何在描述中创建新行

我使用以下内容为php脚本的outlook创建日历邀请。然而，这并没有给我带来新的前景。有办法做到这一点吗？如果你做不到，那就太傻了！

  function addToCalendar($calEmail, $calSubject, $calDesc) 
  {
$calEmail = 'freelance@skinzy.org';
$description = $calDesc;
$message="BEGIN:VCALENDAR
VERSION:2.0
CALSCALE:GREGORIAN
METHOD:REQUEST
BEGIN:VEVENT
DTSTART:20110718T121000Z
DTEND:20110718T131000Z
DTSTAMP:20110525T075116Z
ORGANIZER;CN=TOMS TEST:mailto:system@skinzy.org
UID:12345678
ATTENDEE;PARTSTAT=NEEDS-ACTION;RSVP= TRUE;CN=Yup:mailto:sample@test.com
DESCRIPTION New 'n Line
LOCATION: I AM THE LOCATION
SEQUENCE:0
STATUS:CONFIRMED
SUMMARY: TEST SUMMARY
TRANSP:OPAQUE
END:VEVENT
END:VCALENDAR";
$headers = "From: From Name <From Mail>'n";
$headers .= "MIME-Version: 1.0'n";
$headers .= "Content-Type: text/calendar; method=REQUEST;'n";
$headers .= '        charset="UTF-8"';
$headers .= "'n";
$headers .= "Content-Transfer-Encoding: 7bit";

$subject = "Meeting Subject";
$subject = html_entity_decode($calSubject, ENT_QUOTES, 'UTF-8');

if(mail($calEmail, $calSubject, $message, $headers)) {
    echo "sent";
}else {
    echo "error";
}

  }

这是我遇到问题的DESCRIPTION New 'n Line部分。

将非常感谢任何帮助

Tom
