First, like John_Betong alluded to, sometimes you want to provide default values to avoid isset() calls. But other times you do want the isset() call because the mere existence of a variable, even if empty, might have ramifications elsewhere in the application.
Second, don't confuse the wise goal of writing the least amount of code necessary with the not-so-wise goal of using the least amount of
characters of code possible.
