Writing newlines into files

Hi!

$FTP_FILE="d:\programme\serv-u\ServUDaemon.ini";
$fp = fopen("$FTP_FILE", "a");
$data="\n\n[USER=$username|1]\nPassword=$pw\nHomeDir=d:\\nLoginMesFile=c:\wi
ndows\profiles\flo\my
documents\msg.txt\nDiskQuota=1|301443514202|24963514202\nAccess1=D:\-=Upload
s=-|RWLCP\nAccess2=D:\Moviez|RLP\nAccess3=D:\Music|RLP";
fwrite($fp,$data);
fclose($fp);

That's my code and i want to make newlines in the text file..the file is
text//plain but instead of a newline there are some awesome letters..

Please help me..
