How to fetch data from different blogs into a single web Portal?

I am Working in PHP MySql project, I Have A Page Called Live开发者_如何学Python Information, And Client need this page to function like all the information from different blogs related to some specific topic must be displayed on this page.

So Any Direction On how can it be done?

If the blogs give out an RSS feed you can use an RSS library like Magpie to get at the data.

If they don't, you'll need to get their HTML and parse. You'll most probably have to write a parser for each site. Have a look at web scraping.
