The point here is that the named function is outside the object. That
is, $this-foo() doesn't exist, so $this-{$this-fname}(), does not
work either.
But if you look at

wow.. ${} is more powerful than i had originally though.
Thank you Curt,
With your suggestion, I finally re-wrote the example, and here it is:
?php
function foo() {
echo In foo()br /\n;
}
class a {
var
I need to record the names of functions, and then use them later.
Recently I found the following example within the on-line documentation:
?php
function foo() {
echo In foo()br /\n;
}
$func = 'foo';
$func();// This calls foo()
?
then I supposed that it was easy to extend this concept to

Are you sure about that syntax? I'm not too familiar with Smarty, only
used it once, but I think its $this-some_var(value);
MS and this throws errors on Windows
Smarty has a class method where it calls:
$this-$some_var(somevalue);
and this throws errors on Windows versions of php that i've tried. why
is that?

This does not work as expected (as I expect it at least) and gives the
following error. This seems to result with use of empty(), isset(), and
unset(), perhaps others :
Call to undefined function: empty()
When using :
$foo = 'empty';
if ($foo($var)) print 'worked.';
Of course the
$foo is a string not a PHP function which makes 'empty' a string and not a
function/command.
Am I missing something?

Change the parens around $var to curly braces:
if ($foo{$var}) print 'worked.';

I wish it were that easy. Also, I'm looking for words on WHY this
behavior exists.

?php

Solved.
empty, isset and unset are not functions, they are language contructs,
which results in the error. This makes sense, a workaround is creating
functions like isEmpty (or something similar) and using them. I'll be
submitting a future request soon ;)
Thanks everyone, especially OpenSrc
