In PHP, how do I cache objects with strong typing?

In PHP, caching objects with strong typing can be achieved using various techniques such as serialization and using caching libraries like APCu or Redis. Strong typing helps ensure that the data type of an object is enforced, enhancing type safety and reducing runtime errors.

Here's an example of how to cache an object in PHP with strong typing:


        <?php
        declare(strict_types=1); // Enforce strict typing

        class User {
            private string $name;
            private int $age;

            public function __construct(string $name, int $age) {
                $this->name = $name;
                $this->age = $age;
            }

            public function getName(): string {
                return $this->name;
            }

            public function getAge(): int {
                return $this->age;
            }
        }

        // Caching example using APCu
        function cacheUser(User $user): void {
            apcu_store('user_' . $user->getName(), $user);
        }

        function getCachedUser(string $username): ?User {
            return apcu_fetch('user_' . $username);
        }

        // Usage
        $user = new User('John Doe', 30);
        cacheUser($user);

        $cachedUser = getCachedUser('John Doe');
        if ($cachedUser) {
            echo "User Name: " . $cachedUser->getName() . "<br>";
            echo "User Age: " . $cachedUser->getAge();
        }
        ?>
