I have 2 websites:
website A which is blank and is categorized;
website B which doesn't have categories but has information;
I want php to go to website B, get all the new information that has been added since last visit, and then update websites A database;
now i know basic php but this seems to be out-of-scope so to say :D
so now the question: how to make php go to website B and read all the info? not asking for code, im just wondering under what title could i find the information;
and also, in the php-beginners-difficulty-scale 1 to 10, how hard would it be to accomplish this?
any general advice?
