added a way to enable/disable object support when parsing/dumping
By default, object support is disabled, and instead of throwing an exception when an object is handled, null is returned. If you do need object support, enable it via: Yaml::dump($data, false, true); If you want an exception to be thrown in case an invalid type is handled (a PHP resource or a PHP object), pass true as the second argument: Yaml::dump($data, true, true); The same can be done when parsing: Yaml::parse($data, 2, false, true);
