Call to undefined function create_function()

This is an error raised on using PHP 8.x, on line 33 of file popularity-posts-widget.php.

This can be easily solved like this:

add_action(‘widgets_init’, ‘ppw_widgets_init’);
function ppw_widgets_init() {
? ? return register_widget(“PopularityPostsWidget”);
}

Would be nice to see that plugin working with PHP 8.x
