Whatever implementation details are chosen, they need to be coherent.
I think your proposed behaviour would lead to pretty counter-intuitive
situations:

$foo[NULL] = 33;
if( isset($foo[NULL]) ){
echo $foo[NULL];
}else{
echo '$foo[NULL] is not set'; // Seriously? WTF?
}

The PHP language has basically evolved along the years as a living
creature would do, unlike other languages that have actually been
designed "on purpose", and it has lots of obvious inconsistencies. But
you are basically suggesting that there's no place for loosely typed
languages and I disagree with that. I'm very happy that I don't need to
write three overloaded versions of the same method just to cope with all
the expected input data types.

Whatever, if you do web stuff and you prefer strong typing I believe you
do have quite a choice, from Java to .NET (VisualBasic and C#). Don't
stick with PHP if you are not going to enjoy its good parts.
