Hi,

You have to understand that 'gettext()' is a PHP function that performs a
lookup in a message catalog, and the way you wrote it, $var is substituted
_before_ the lookup in the message catalog. This doesn't work because you
cannot know all possible values of $var in advance. The solution is to
substitute $var _after_ the message catalog lookup. Like this:

  printf (gettext ("how are you %s "), "$var")
