How do I...save a string to a remote file via FTP?

[s_shrum]

I'm writting a WAN IP extraction & publishing script and are on the cusp of completion. Just one issue remains...

I've retrieved (via cURL) the router page data and stored it into a string. I would like to save this string as a file to my remote server over FTP. Only problem is that it looks like all the FTP functions for 'writting' data want an actual filename, not a string of text.

Is there a way to write a string to a file via FTP without having to write the string to a file locally first?

TIA
