Iter Laravel Package
php-standard-library/iter
Inspect and reduce any PHP iterable (arrays, generators, iterators) with small, focused helpers from PHP Standard Library - Iter. Designed for common iteration tasks and consistent behavior across iterable types.
Utility functions for inspecting and reducing iterables - arrays, generators, and iterators
Frequently asked questions about Iter
- How can I use this package to optimize Laravel Eloquent query results processing?
- Use `iter()` to wrap Eloquent collections or cursor results, then chain methods like `filter()`, `map()`, or `reduce()` for lazy processing. For example, `Model::cursor()->iter()->filter(fn($model) => $model->active)->map(...)` avoids loading all records into memory at once, ideal for large datasets or API responses.
- Does this package work with Laravel’s queue jobs for batch processing?
- Yes. The lazy evaluation model is perfect for queue jobs—process iterables in chunks without materializing the entire dataset. For example, `iter($largeArray)->chunk(100)->each(fn($chunk) => dispatch(new ProcessChunkJob($chunk)))` integrates smoothly with Laravel’s queue system.
- What Laravel versions and PHP versions does this package support?
- The package requires PHP 8.1+ and is designed for Laravel 10+. It leverages modern PHP features like iterable return types and named arguments, which align with Laravel’s latest versions. Check the [PHP Standard Library docs](https://php-standard-library.dev) for exact compatibility notes.
- How does performance compare to Laravel’s built-in Collection class for common operations?
- For lazy operations (e.g., `map()`, `filter()`), this package often outperforms `Collection` in memory usage, especially with large datasets, since it avoids eager loading. However, `Collection` may still be faster for simple, small-scale operations due to Laravel’s optimizations. Benchmark with your specific use case.
- Can I use this in Laravel Blade templates for dynamic data rendering?
- Yes, but with caution. While you can pass iterables to Blade, lazy pipelines (e.g., `iter($items)->filter(...)`) won’t work directly in `@foreach` loops. Convert to an array first with `iter($items)->toArray()` or use it in PHP logic before passing data to the view.
- What alternatives exist for functional iteration in Laravel, and why choose this package?
- Alternatives include `symfony/collection` or `league/collection`, but this package is lighter, PHP 8.1+ optimized, and focuses solely on iterables (arrays, generators, iterators). It avoids Symfony’s heavy dependencies and provides a more modern, composable API tailored for Laravel’s lazy-processing needs.
- How do I test code that uses lazy iterables in Laravel’s testing environment?
- Use Laravel’s testing tools like `assertEquals()` with `iter($expected)->toArray()` for comparisons. For generators, mock them with `Mockery` or `Pest` and verify output by iterating through results. Example: `iter($generator)->take(5)->toArray()` ensures you test finite subsets without full materialization.
- Will this package conflict with existing Laravel packages like spatie/array-to-object?
- No, it’s designed for low coupling. Use `iter()` to transform arrays or generators before passing them to `spatie/array-to-object` or other packages. For example, `iter($array)->map(...)->toArray()` can preprocess data before conversion.
- How do I handle mixed iterables (e.g., arrays, generators, IteratorAggregate) in Laravel?
- This package normalizes iterables automatically, so you can chain methods like `iter($mixed)->filter(...)` without explicit type checks. For strict typing, use PHP’s `is_iterable()` or `instanceof` checks, but the package handles most cases seamlessly in Laravel’s dynamic context.
- Are there plans to add Laravel-specific utilities, like integration with API Resources or Artisan commands?
- The package is framework-agnostic but welcomes contributions for Laravel-specific helpers. Check the [GitHub issues](https://github.com/php-standard-library/php-standard-library/issues) or propose a PR for features like `iter()->resource()` or Artisan command integrations. The team encourages community-driven Laravel extensions.
