Ok there is more what i like but this is biggest chages for me.

Maybe someone can tell me im crazy but i realy like strongly typed languages. And with 7.4 relase php is closer to them. (and more will come in 8.0) .

Now my Model classes can look like this

class UserIndexViewModel
{
    protected int $id;
    protected string $email;
    protected int $groupId;
    protected string $groupName;
    protected bool $isActive;
    protected bool $isAdmin;
    protected FrozenTime $created;
    protected FrozenTime $modified;

    /**
     * UserIndexViewModel constructor.
     * @param int $id
     * @param string $email
     * @param int $groupId
     * @param string $groupName
     * @param bool $isActive
     * @param bool $isAdmin
     * @param FrozenTime $created
     * @param FrozenTime $modified
     */
    private function __construct(int $id, string $email, int $groupId, string $groupName, bool $isActive, bool $isAdmin, FrozenTime $created, FrozenTime $modified)
    {
        $this->id = $id;
        $this->email = $email;
        $this->groupId = $groupId;
        $this->groupName = $groupName;
        $this->isActive = $isActive;
        $this->isAdmin = $isAdmin;
        $this->created = $created;
        $this->modified = $modified;
    }

    /**
     * @return int
     */
    public function getId(): int
    {
        return $this->id;
    }
// ...
}

One think i missing now is array of objects. In 7.4 you can not define it. You define simply just array however it is here a workaround and it can be defined in doc blocks:

   /**
     * Returns populated array f ViewModel
     *
     * @param \Cake\Datasource\ResultSetInterface|\Iam\Model\Entity\User[] $data
     * @param IdentityInterface $identity
     * @return array|\Iam\ViewModel\UserIndexViewModel[]
     */
    public static function prepare(ResultSetInterface $data, IdentityInterface $identity) : array
Enter fullscreen mode Exit fullscreen mode

PHP 8.0 (which is in RC stage i think) will bring Union types, so that can change.

What do you think about PHP now? Do you like weakly typed or strongly typed languages more?

Why do you still use doc block if every property including the return type is type hinted? It's redudant.

They are rewritten functions (i used 7.3 before)... but sometimes i have to use them for example if my return type is Array of something.... i cant return function xy() : User[] but only function xy(): array so i add @return array|User[] to docblock...

PS: and PhpStorm returns me errors when definition in docblock is missing... (i have to configure it to do not doing it)
