Are there any recommended PHP libraries or frameworks for handling tree structures efficiently?

When dealing with tree structures in PHP, it is recommended to use libraries or frameworks that provide efficient methods for handling and manipulating these structures. One popular library for this purpose is the "Nested Set Model" which allows for efficient retrieval of tree data. Another option is to use frameworks like Laravel which has built-in support for handling tree structures through its Eloquent ORM. 

// Example using Nested Set Model library
// Install the library using Composer: composer require kalnoy/nestedset
use Kalnoy\Nestedset\NestedSet;

// Define your model class
class Category extends \Illuminate\Database\Eloquent\Model
{
    use NestedSet;
}

// Usage
$root = Category::create(['name' => 'Root']);

// Add child categories
$child1 = $root->children()->create(['name' => 'Child 1']);
$child2 = $root->children()->create(['name' => 'Child 2']);

// Retrieve descendants of a node
$descendants = $root->descendants()->get();
