What are the benefits and drawbacks of using a static counter versus a Window Manager approach for managing multiple instances of a class in PHP?

When managing multiple instances of a class in PHP, using a static counter can simplify the process by keeping track of the number of instances created. However, a Window Manager approach allows for more flexibility and control over the instances by providing methods to manipulate them individually.

class MyClass {
    private static $instanceCount = 0;
    
    public function __construct() {
        self::$instanceCount++;
    }
    
    public static function getInstanceCount() {
        return self::$instanceCount;
    }
}

// Example usage
$instance1 = new MyClass();
$instance2 = new MyClass();

echo MyClass::getInstanceCount(); // Output: 2
