Rob,
I agree with you entirely. It's possible to write this code probably
a hundred different ways which, to me, also noting the number of
posts the topic has generated, indicates that it should be supported
in the language. A common convention for a common operation seems
like a sensible goal to me. As nice as it is to be able to roll your
own, code sharing is facilitated when we include de facto behaviors.
The single implementation close to the metal would also help with
speed and code verifiability.
Thanks,
-Noah

If it were possible at all to make a function accept unset

unfortunately, it doesn't seem to be possible, unless you'd
suppress every
function call with a @, which I don't think is the way to go in
this case.
So if it would be possible somehow to create your own isset()-like
functions
in PHP-code, I'd say implement something that would make that
possible, and
ingore the whole ifsetor() discussion from that moment on. People
would be
free to write whatever function they'd prefer.
Voila!
function ifsetordefault( $array, $key, $default=null )
{
if( isset( $array[$key] ) )
{
return $array[$key];
}
return $default;
}
echo ifsetordefault( array( 1 => 'One', 2 => 'Two' ), 3, 'Three' );
Or if you prefer:
function ifsetpathordefault( $array, $path, $default=null, $sep='/' )
{
$pathBits = explode( $sep, $path );
$nest = $array;
foreach( $pathBits as $pathBit )
{
if( !isset( $nest[$pathBit] ) )
{
return $default;
}
$nest = $nest[$pathBit];
}
return $nest;
}
And yet, I'd still prefer an internal function to do this MUCH MUCH
MUCH
faster and then I'd also never need to run across the problem of
naming
collisions with other libraries that implement the same code :)
Cheers,
Rob.
