How to display posts from the walls of social networks in one feed on the site?

Question

PHP

Good afternoon dear gurus-programmers.
I have a task. It is necessary to display on the site the latest posts from three social networks Google+, Facebook, VK in one list using php. Having rummaged on the Internet, I did not find a more or less intelligible description of the solution to this problem. I am a beginner programmer. The thought about data parsing is spinning in my head. Maybe someone has already implemented something like this, tell me where to dig?
Many thanks in advance and have a great day everyone!

Answer 1

1. Register applications in all social networks. networks.
2. Through the API you get access to your records.
3. Display what you need.

Answer 2

They all have an API. There is a lot of documentation for each (VK for sure), you get the last post and display it beautifully.
There would be time, I would give an example for Vk. Just take it out, no big deal.
