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:
function foo() {
echo "In foo()\n";
}
class a {
var $fname;

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

I need to record the names of functions, and then use them later.
Recently I found the following example within the on-line documentation:
\n";
}
$func = 'foo';
$func();// This calls foo()
?>
then I supposed that it was easy to extend this concept to objects and
wrote the following case:

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");

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

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 ;)

$foo is a string not a PHP function which makes 'empty' a string and not a
function/command.
Am I missing something?
