Коментарии
If you creates methods by using classkit_method_add(), they are not visible in get_class_methods().
class A
{
public function foo()
{
return "foo!\n";
}
}
classkit_method_redefine('A','bar','','return "bar !\n";',CLASSKIT_ACC_PUBLIC);
print_r(get_class_methods('A'));
// writes only "foo"
