Favicons for all!
It's really easy to use this!
You'll need PHP (5.6+ or 7 is recommended)
By default favicon images are stored in 'cache' directory, but you can change this easily by adjusting the constant at the top of the index.php file.
It's currently set to the same root directory as this code:
$_CACHE_PATH = "cache";
But you can change it to write to somewhere else, e.g.:
$_CACHE_PATH = "../favicon_cache"; // one directory up
Make sure that the cache directory is writable by the web application user, or whoever triggers the execution of the PHP script.
