Dos vs. Unix newline

I have found that some windows OFX servers are sensitive to the newline method when sending OFX requests.  Unix style uses a linefeed (LF) which can be created on unix systems as "\n".  DOS/Windows style uses a carriage return linefeed (CRLF) which can be created on unix systems as "\r\n".  Windows servers seem to like the DOS style and might not work with the unix style.  A typical error from a windows server in this situation would look like this:

OFXAdapter: Failed to parse request: Unable to parse an atomic field "OFXRequest.Headers.OFXHeader": unable to find end delimiters "
".
Remaining unparsed data:
100
DATA:OFXSGML

(note the 100 line is sent as OFXHEADER:100)

One handy way to convert a string to DOS style in php is:

$data = str_replace("\n", "\r\n", $data);

This assumes that the $data string you generate uses only \n.
