I'm guessing one of two things: the fopen call failed (and you're not checking if it succeeded by seeing if $file !== false ), or the double-use of _returntransfer AND _file is not acting as you expect.

returntransfer tells curl to return the retrieved data in the exec call, instead of outputting it directly to the browser. I suspect that if you did $data = curl_exec($curl); file_put_contents('ftpfile/file.csv', $data) $data = curl_exec($curl); file_put_contents('ftpfile/file.csv', $data) you'd end up with a properly populatd file. So... either remove the returntransfer option, or eliminate the whole _file business and output the file yourself using what the _exec call returns.
