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

First Method in which we can search it from fevicon.ico if found than it will show it up else not

';
        }
        else
        {
            echo "Not found";
        }
    ?>

In other method you can search for icon and get that icon file

    ';
function getFavicon($site)
{
            $html=file_get_contents("http://www.".$site);
            $dom=new DOMDocument();
            @$dom->loadHTML($html);
            $links=$dom->getElementsByTagName('link');
            $fevicon='';

            for($i=0;$i < $links->length;$i++ )
            {
                $link=$links->item($i);
                if($link->getAttribute('rel')=='icon'||$link->getAttribute('rel')=="Shortcut Icon"||$link->getAttribute('rel')=="shortcut icon")
                {
                    $fevicon=$link->getAttribute('href');
                }
            }
            return  $fevicon;
}
?>
