How to get a website's favicon with PHP?

Question

I want to get, requested website\'s favicon with PHP. I have been recommended using Google\'s favicon service but it is not functional. I want to do something on my own but

Answer 1

Use the S2 service provided by google. It is as simple as this

http://www.google.com/s2/favicons?domain=www.yourdomain.com

Scraping this would be much easier, that trying to do it yourself.
