Marian Kostadinov ([stochnagara on Twitter](https://twitter.com/stochnagara)) replied to Friday's email about DTOs and value objects to tell me about `readonly` classes, which can be done in PHP 8.2.
|
||
|
|
|
||
|
|
Looking at the previous class:
|
||
|
|
|
||
|
|
```php
|
||
|
|
class AccountDetails {
|
||
|
|
|
||
|
|
public function __construct(
|
||
|
|
public readonly string $accountNumber,
|
||
|
|
public readonly string $sortCode,
|
||
|
|
) {}
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Instead of setting each property as `readonly`, the whole class can instead be marked as `readonly`:
|
||
|
|
|
||
|
|
```php
|
||
|
|
readonly class AccountDetails {
|
||
|
|
|
||
|
|
public function __construct(
|
||
|
|
public string $accountNumber,
|
||
|
|
public string $sortCode,
|
||
|
|
) {}
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Thanks for the suggestion, Marian!
