Maybe I'm using "reentrant" incorrectly, but here is what I mean...
class Test {
function __get($nm) {

elseif ($nm == 'y')
return 'y';
elseif ($nm == 'xx')
return 'x';
}
function func() {
return $this->xx;

}
$t = new Test();
print $t->y . "\n";
print $t->xx . "\n";
print $t->x . "\n";
print $t->func() . "\n";
I would expect the following code to output:
y
x
x
x
But instead, it outputs:
y
x
x
Is this a bug? This limitation is not documented (maybe it should be?).
its not a bug, I believe its documented somewhere how this works.
bottom line __get() does not work from 'inside' the class/object,
so do something like instead:
function func() {
return $this->__get('xx');
}
which may not please the soul, but does work ;-)
Hehe, my soul is hard to please...=P
Actually, __get() does work from inside the class. In the sample code I
posted, func() does indeed return 'x' when called from main. It does not
work when called from within a call to __get(). In other words,
$this->attribute does not work if __get() appears anywhere in the call
stack.
Its just a small annoyance.
I think it would be more annoying if __get() would be recursively called
to infinity.
