Constructor property promotion

WTF!?

class Customer
{
    public string $name;
    public string $email;
    public Date $birth_date;

    public function __construct(
        string $name, 
        string $email, 
        Date $birth_date
    ) {
        $this->name = $name;
        $this->email = $email;
        $this->birth_date = $birth_date;
    }
}

Nice!

class Customer
{
    public function __construct(
        public string $name, 
        public string $email, 
        public Date $birth_date,
    ) { }
}

Fluent sintaxe

WTF!?

$mary = User::first();

$payment = new Payment(12.98, '2023-01-09', $mary, 4.76);
$payment->process();

Nice!

$mary = User::first();

(new Payment)
   ->for($mary)
   ->amount(12.98)
   ->discount(4.78)
   ->due('2023-01-09')
   ->process();

Encapsulate contexts

WTF!?

public function makeAvatar(string $gender, int $age, string $hairColor)
{
   ...   
   return 'https://...';
}

$user = User::first();

makeAvatar($user->gender, $user->age, $user->hairColor);

Nice!

public function makeAvatarFor(User $user): string
{
   ...
   return 'https://...';
}

$user = User::first();

makeAvatarFor($user);
