Json

All DTOs are Json serializable, meaning that they inherit from the JsonSerializable interface. This means that when using json_encode(), the DTO automatically ensures that its properties are serializable by the encoding method.

$person = new Person([
    'name' => 'Rian Dou',
    'age' => 29
]);

echo json_encode($person);

The above example will output the following Json string;

{
    "name":"Rian Dou",
    "age":29
}

toJson()

You can also perform json serialization directly on the DTO, by invoking the toJson() method.

$person = new Person([
    'name' => 'Rian Dou',
    'age' => 29
]);

echo $person->toJson(); // The same as invoking json_encode($person);

Populate from Json

To populate a DTO directly from a Json string, use the fromJson() method.

$json = '{"name":"Miss Mossie Wehner Sr.","age":28}';

$person = Person::fromJson($json);

echo $person->name; // Miss Mossie Wehner Sr.
