New line characters and carriage returns

Ok, don't know what I am doing wrong here...but for some reason I cannot get new line or carriage return characters to work correctly... For example, When I send some emails, I try $msg .= "From: me@mydomain.com\r\n Content-Type: text/plain\r\n" And it doesn't work correctly... the Content Type shows in my mail body.... More importantly, I'm trying to write a system logger $fileName = 'errors.'.date('dmY').'.log'; $error = date('h:i:s').' '.$script.' '.$error.'\n'; error_log ($error, 3, '/var/www/killerspin/logs/'.$fileName); but the output into my log file shows the \n but does not use it.
