Hello!

Suppose I have the following code:

$a = array('a'=>1, 'b'=>2);
echo empty($a['c'])?'empty':'not empty';
echo $a['c'];

Why doesn't the 2nd line output a warning when error_reporting is set
to E_ALL? Is empty() some kind of special function where the validity
of indices is not checked? If that is the case, I have two questions:

1. Will this behavior persist in future versions of PHP?
2. Are there other functions or a general rule where PHP doesn't
output warnings when a nonexistant index is given?
