Hi all,
I want to make a site like ShopMania.
I want a way to get data from another site, and add or update(if it exist already) to my database.
For example X has a website(shop online), and with his approval!, I want to get his products and add them to my database, and after 10 days(for example) if X makes an update to some products, that update will be made automatically to my database.
I hope you understood what I want. I want an idea to make that(for example I can upload a file to that site to generate a table, and my website will read that file every day to check if X made some change).
I want an idea which is efficiency(if I have 50 sites), and secure.
Thanks in advance and sorry for my poor english.
