Fixed Phalcon\Support\Collection::get() returning the wrapping object's mangled property table when called with $cast = 'array' on a stored object (e.g. a nested Phalcon\Config\Config, which Config::setData() wraps around every array value). The previous implementation called settype($value, 'array') unconditionally, which on an object exposes PHP's null-prefixed internal protected-property names ("\0*\0data", "\0*\0lowerKeys", etc.) instead of the intended array form, so $config->get('outKey', [], 'array')['inKey'] raised Notice: Undefined index. The cast branch now special-cases 'array' for objects exposing a toArray() method and delegates to that method; scalar casts (int, bool, float, string, null, object) and 'array' on a plain stdClass (no toArray()) are unchanged

Thanks
