> Since the [PHP RFC: Readonly properties 2.0](https://wiki.php.net/rfc/readonly_properties_v2)will be available on PHP 8.1 this repository will be archived.

It enforces immutability on initialized properties.

Immutable properties can be really handful to avoid `getter/setter` boiler-plate or just enforce immutability for specific objects.

We see it as specially useful for the following use cases: **VOs**, **DTOs**, **Commands**, **Events** and **ViewModels**.

### Installation

[](#installation)

```
$ composer require codelicia/immutable

```

### Usage

[](#usage)

Enable immutability on your classes just by plugging the `ImmutableProperties` trait on it.

```
final class User
{
    use \Codelicia\ImmutableProperties;

    public string $name;
    public int $age;
}

$user       = new User;
$user->name = "@malukenho";

// this will crash
$user->name = "Throws exception as the property name cannot be reassigned";
```

We recommend you create a `__construct` to make the object stay in a valid state right after the instantiation of it, but it is up to you and your necessity.

```
final class User
{
    use \Codelicia\ImmutableProperties;

    // It is fine to leave the properties visibility as public as the `ImmutableProperties`
    // trait will not allow it to change after it is being initialized in the
    // class constructor
    public string $name;
    public int $age;

    public function __construct(string $name, int $age)
    {
        $this->init(); // The `init()` method must be called here

        $this->name = $name;
        $this->age = $age;
    }
}
```
