Jason, you are absolutely right.. this is not about input filtering at all.
It's about replacing:
$x = (isset($ANY_var) ? $ANY_var : 'Default Value');
by
$x = ifsetor($ANY_var, 'Default Value');
So, Robert's solution is no real solution if you ask me. But again, it would
be best, if there was no ifsetor() at all,
I must say I fully agree; I don't see any use in putting extra functions
in the PHP namespace just because people don't want to type a couple of
extra characters.
but that users would have the
power to create such a function themselves in the php code space. I have no
clue how though...
Well my code has nothing to do with filtering. It's all about retrieving
a default value if one is not set in response to the poster to which I
replied. But yes, I was hasty with it in my eternal lack of wisdom, and
of course forgot about scalars. For the record, I am indeed in favour of
something that allows the choice of a value from a series of values for
which some may not be set-- without the generation of not set warnings
:)
On that note, how comes there's a $GLOBAL array and not a $LOCAL array
for vars declared in the immediate scope :)
because, by definition, $LOCAL would at all times be a part of $GLOBAL.
And besides, why would you ever want $LOCAL? $GLOBAL is a way to reach
the global scope from the local scope. When being in global scope, you
never *have* a local scope, and the other way around, when being in
local scope, you can reach all variables directly anyway, so there's no
use for $LOCAL. Then, expecting the response "why is there a $GLOBAL
array in global scope?" you might want to say that $GLOBAL is a
superglobal just because the "global" scope can be seen as a "local"
scope in a broader perspective. Well... that's my view on it anyway...
Cheers,
Rob.
