create_function() is deprecated

[morebrackets]

create_function() has been deprecated and all instances should be converted to Anonymous functions (closures).

i.e.:
rock.php:451

From:
$name = preg_replace_callback("/_([a-zA-Z])/", create_function('$match', 'return strtoupper($match[1]);'), $name);

To:
$name = preg_replace_callback("/_([a-zA-Z])/", function ($match) {return strtoupper($match[1]);}, $name);
