A lightweight PHP package implementing common design patterns like **Singleton** and **Factory**. Useful for clean and efficient object management in PHP projects.

📌 Features
----------

[](#-features)

✅ **Singleton** – Ensures only one instance of a class exists.
✅ **Factory** – Creates objects without specifying the exact class type.

Polyfills (Extra Feature)
-------------------------

[](#polyfills-extra-feature)

Older versions of PHP may not have certain function available. For example `json_validate()` is not available in PHP versions older than 8.3.0. This class transparently implements all this functionality as a shim / polyfill without disturbing environments where such functions are available.

Functions currently implemented in the polyfills

✅ **`json_validate`**

📥 Installation
--------------

    public function getData(): string
    {
        return $this->data;
    }
}

$instance1 = MySingleton::getInstance();
$instance2 = MySingleton::getInstance();

echo $instance1->getData(); // Hello, Singleton!
var_dump($instance1 === $instance2); // true (Both refer to the same instance)
