It's a kind of promoting binary safety. Not the passed number
of parameter passed to zend_parse_parameters() is important
but what modifies are used to describe the parameters.
Since a string is not only meant to be characters from A-Z
but in fact can be anything including binary data, it's a
good idea [tm] to always get the point to the string AND it's
length and work with both when making further function calls
(if possible).
