I would like to create a system which can manage all my websites from one page. All options of managing are let's say done or I know how to do them, except from editing and creating files on an external server.
I would like to know what is the best way to save files on exteral server. I would like to chang few files at once and would be nice not to leave administration panel. It is important to keep the whole system safe - that nobody could edit it without accesing administration panel.
I thought about changin chmods on each website using a local script and chmod() but then i cant access the files because http:// is not writable protocole i used fwrite() function.
Can you give me some tips how should I create that?
