To simply enlist all methods and properties of an object simply write:

<?php ReflectionObject::export($yourObject); ?>

,which will cause an var_export-like output.

class a {

    public function __get($key){
        $r = new ReflectionObject($this);
        if($r->hasConstant($key)){ return $r->getConstant($key); }
    }
}
class b {
    public function getA(){
        return new a();
    }
}
$b = new b();
var_dump($b->getA()::abc);
var_dump($b->getA()::def);
