New Comment:
I realize it isn't a function (took a couple time of saying empty(
someFn( ) ) to get that through to me)... I haven't, however, looked at
the source for empty() so I'm don't know what it's BC is (or what the
issue is).
The issue I run into is one of (html) input validation. With the
behavior of trim() (per our short conversation on bug #31302) it
doesn't seem that there is a clean, efficient way of checking for
people entering a string of spaces or non-breaking spaces ( ) in
the place of legit input.
Am I missing something completely?

We can't change this due to BC reasons, also, it doesn't fit a
particular language construct (empty is NOT a function!)

Description:
------------
I thought that this used to be the behavior of empty()...
It would be nice of empty() returned true when passed a string which
only had spaces, tabs, or newline characters in it.
Reproduce code:
---------------
$foo = ' ';
if ( empty( $foo ) ) {
echo "foo is empty";
} else {
echo "foo is NOT empty";
}//if
---
output is: 'foo is NOT empty'
Expected result:
----------------
expected output: 'foo is empty'
