What are some best practices to consider when implementing the Flyweight Pattern in PHP to ensure efficient resource utilization?

When implementing the Flyweight Pattern in PHP, it is important to consider efficient resource utilization by reusing shared objects to minimize memory usage. To achieve this, we can create a FlyweightFactory class to manage the creation and retrieval of shared Flyweight objects. Additionally, we can use a key to identify and retrieve the shared Flyweight objects from the FlyweightFactory. 

<?php

class FlyweightFactory {
    private $flyweights = [];

    public function getFlyweight($key) {
        if (!isset($this->flyweights[$key])) {
            $this->flyweights[$key] = new ConcreteFlyweight();
        }
        return $this->flyweights[$key];
    }
}

interface Flyweight {
    public function operation();
}

class ConcreteFlyweight implements Flyweight {
    public function operation() {
        // Perform operation
    }
}

// Usage
$factory = new FlyweightFactory();
$flyweight1 = $factory->getFlyweight('key1');
$flyweight2 = $factory->getFlyweight('key2');
$flyweight1->operation();
$flyweight2->operation();
