Favicon with php?

[Fulla]

Been reading lots of tutorials on this. I've managed to generate a favicon.ico & upload into my root folder.

The problem is all of them then give a next step of adding a html line into your index.
My index is however in php, so not sure how to accomplish this?

I came across a php tut, tried it but also failed:

PHP Code:

<?php
    require_once('favicon.inc.php');

    $favicon = new favicon('http://www.controlstyle.ru/', 0);
    $fv = $favicon->get_output_data();

    if ($fv!=='')
    {
        header('Content-type: image/png');
        echo $fv;
    }
?>

Please help, thank you.
