regex - 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 don't know regex usage.

I found a class on Google that works on most cases but it has unacceptable error rate. You can have a look here: http://www.controlstyle.com/articles/programming/text/php-favicon/

Can somebody please help me about getting favicon using regex, please?

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.
