What are some recommended PHP libraries or resources that can assist in efficiently organizing and manipulating arrays based on specific criteria like category grouping?

When working with arrays in PHP, it's common to need to organize and manipulate the data based on specific criteria, such as grouping items by category. To efficiently handle this task, using PHP libraries like Laravel Collections or Symfony's ArrayHelper can provide powerful tools for sorting, filtering, and grouping arrays based on different criteria. 

// Example using Laravel Collections to group array by category
use Illuminate\Support\Collection;

$data = [
    ['name' => 'Item 1', 'category' => 'A'],
    ['name' => 'Item 2', 'category' => 'B'],
    ['name' => 'Item 3', 'category' => 'A'],
    ['name' => 'Item 4', 'category' => 'B'],
];

$collection = collect($data);

$grouped = $collection->groupBy('category');

$grouped->each(function ($items, $category) {
    echo "Category: $category\n";
    foreach ($items as $item) {
        echo $item['name'] . "\n";
    }
});
