create_function() is deprecated

  • Hi,
    on PHP 7.2 is on line 62 the Function create_function() declared as deprecated.

    With this Code is the Issues

    add_action('widgets_init', function() { return register_widget("Safe_PHP_Code_Widget"); });

    But the eval error can’t I fix it.

    safe-php-code-widget.php(27) : eval()'d code on line 8
