Scraping public posts and comments by user?

Hello!

I need to scrape public posts and comments from a user and collect it all in text to analyze.
The plan is to not use the Facebook API since then I need the user to login with their account, I just need to collect what they posted publicly and get it as pure text for analyzing.

I would be very happy if this could run as a simple PHP for javascript application.

Do anyone here have any idea on how to do this?

I can do that but manually, no software or not can be used.
Let me if this works for you or not.

The problem is that I need it to happen automatically when someone pushes a button :/

Ok

Somewhere i wrote same script in .net. If its interesting for you, drop me a pm.
