I ran into something very, very interesting today. Google Favicon API
(A Favorite Icon API). It’s an API that allows you to pull websites Favicons, plus the API dynamically converts the image into a PNG format. This actually comes at a great time because I was just thinking the other day that since I have the option to add offsite URL’s to my site now. Would’nt it would be supa cool if I could also included their Favicon? To beak it down if you look into my site’s right side navigation you will see the “Links” category. Well I thought it would be nice, I mean supa cool if I had a script that could automatically include the corresponding sites Favicons. And BAM! Thanks Google Favicon API. I wrapped this APIs up with some cURL and a little PHP and now I have a working PHP function. I don’t know much about the Google Favicon API but it looks like it’s been around for about a year. So it’s a good chance that this API could suddenly up and move or disappear all togehter. Basically what I’m saying is I don’t know how long the good times will last. So in my opinion I suggest you consider the use of this script temporary until you can get the time to build a much reliable one yourself.
$fp = fopen ('folder/'.$filName.'.png', 'w+');
$ch = curl_init('http://www.google.com/s2/favicons?domain='.$var);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
