how to detect favicon (shortcut icon) for any site via php ?
i cant write regexp because is different in sites..
In the address bar, enter chrome://favicon/ , followed by the url.
A favicon (/ˈfæv. ɪˌkɒn/; short for favorite icon), also known as a shortcut icon, website icon, tab icon, URL icon, or bookmark icon, is a file containing one or more small icons, associated with a particular website or web page.
Nowadays, favicons are displayed right above the address bar regardless of whether the website is bookmarked or not. And in the small chance that a website doesn't have a favicon, the browser will display a generic browser symbol. 2. In addition to the address bar, favicons can also be found in the browser history.
You could use this address and drop this into a regexp
http://www.google.com/s2/favicons?domain=www.example.com
This addresses the problem you were having with Regexp and the different results per domain
