How does object instantiation impact performance in PHP when dealing with multiple objects?

When dealing with multiple objects in PHP, object instantiation can impact performance due to the overhead of creating new objects in memory. To improve performance, you can implement object pooling, where a pool of pre-created objects is maintained and reused instead of creating new objects each time. 

class ObjectPool {
    private $objects = [];

    public function getObject() {
        if (empty($this->objects)) {
            return new YourObject();
        } else {
            return array_pop($this->objects);
        }
    }

    public function releaseObject($object) {
        $this->objects[] = $object;
    }
}

// Example usage
$pool = new ObjectPool();

$obj1 = $pool->getObject();
// Use obj1

$pool->releaseObject($obj1);

$obj2 = $pool->getObject();
// Use obj2
