// ...or try
$container->fromJSON('{"foo": "what", "bar": "foo"}');


// fetch all properties as array
$container->toArray(); // -> ['foo' => 'what', 'bar' => 'foo']
// or JSON
$container->toJSON(); // -> {"foo": "what", "bar": "foo"}
// JSON via JsonSerializable
$json = json_encode($container); // -> {"foo": "what", "bar": "foo"}

//non-existing properties will be ignored:
$container->nope = 'what';
