Is there a way to overload the empty() logic for custom classes on PHP?
for example:

class X implements Stringable {
    private string $value;
    public function __toString(): string {
        return ''; # not even checking the values, always empty
    }
    # doesn't matter for the obj, only for protected properties, but
    # will not cause error on the private here...
    public function __isset(string $value): bool {
        return false;
    }
}

And a simple test

    public function testXisEmpty(): void {
        $actual = new X();
        $this->assertTrue( empty($actual) );
    }

  ✘ X is empty
   ┐
   ├ Failed asserting that false is true.

Is there any way to make empty() respect the toString value? or is there something like toBool? or isset for the object and not just a field?

Could not find anything on the manual but I also spend a lot of time looking at property overloads before i learned class overloads are called “magic” methods, so I might just be missing the right nomenclature…
