it’s for php to know how to handle the parameters,
%d – the argument is treated as an integer, and presented as a (signed) decimal number.
%s – the argument is treated as and presented as a string.
in your examples, $slug is a string and $this->id is an integer
look at http://www.php.net/manual/en/function.sprintf.php for more info
