Laminas Filter Laravel Package
laminas/laminas-filter
A collection of reusable data filters for PHP apps. Provides string and numeric normalization, file and HTML filters, and a plugin manager to compose filter chains. Useful for sanitizing and transforming input consistently across Laminas and other frameworks.
Programmatically filter and normalize data and files
Frequently asked questions about Laminas Filter
- Can I use laminas/laminas-filter in Laravel without conflicts with Illuminate\Validation?
- Yes, but with caution. Laminas Filter is designed for standalone use, so you can integrate it via Composer without direct conflicts. Use it for niche cases like recursive array filtering or custom transformations not covered by Laravel’s Form Requests or Str helpers. Avoid overlapping functionality by clearly separating responsibilities—for example, use Laminas for complex data normalization and Laravel’s validation for rules.
- What Laravel versions does laminas/laminas-filter support?
- Laminas Filter itself doesn’t enforce Laravel version constraints, but it requires PHP 8.1+. For Laravel compatibility, ensure your project’s PHP version aligns with the Laminas package’s requirements. Test thoroughly, as Laravel’s internal utilities (e.g., Str::snake_case) might behave differently than Laminas filters. No official Laravel integration exists, so manual testing is critical.
- How do I install and set up laminas/laminas-filter in a Laravel project?
- Run `composer require laminas/laminas-filter` to install. No Laravel-specific configuration is needed, but you’ll need to manually integrate it—typically in a service class, middleware, or Form Request handler. For example, inject the `Laminas\Filter\FilterChain` into a service and apply filters to user input before validation. Avoid autoloading conflicts by prefixing classes or using namespaces.
- Does laminas/laminas-filter support recursive filtering of nested arrays?
- Yes, Laminas Filter includes array-aware filters like `Laminas\Filter\ArrayObject` and recursive implementations. You can chain filters to process nested structures, such as sanitizing all string values in a deeply nested array. This is useful for APIs or forms with complex payloads, but test edge cases like mixed-type arrays to ensure predictable behavior.
- Are there performance concerns with laminas/laminas-filter in production?
- Performance impact is minimal for typical use cases, as the package is lightweight. However, recursive filtering on large arrays or high-traffic APIs could introduce overhead. Benchmark critical paths and cache filter chains if reusing them frequently. Compare against Laravel’s native solutions (e.g., `Str::*` helpers) for your specific workload to justify the dependency.
- Can I create custom filters for laminas/laminas-filter?
- Absolutely. Implement the `Laminas\Filter\FilterInterface` or extend `Laminas\Filter\AbstractFilter` to create reusable custom filters. For example, build a filter to normalize timestamps or strip HTML tags. Document your filters clearly and test them alongside built-in ones to ensure consistency in your pipeline.
- What’s the difference between laminas/laminas-filter and Laravel’s Str helpers?
- Laminas Filter offers a broader, more structured approach with chaining, recursive processing, and extensibility, while Laravel’s Str helpers are lightweight utilities for common string operations. Use Laminas for complex, reusable filtering logic (e.g., multi-step transformations) and Str helpers for simple, one-off tasks. Avoid redundancy by auditing overlapping functionality.
- Is laminas/laminas-filter actively maintained? Should I use it in production?
- Maintenance appears limited—low GitHub activity and a suspicious future release date (2025-11-15) suggest potential issues. Proceed with caution: evaluate whether its features justify the risk. For production, consider alternatives like `symfony/filter` or Laravel’s built-in tools unless you need Laminas-specific functionality. Monitor the repo for updates or fork it if critical.
- How do I integrate laminas/laminas-filter with Laravel’s Form Request validation?
- Use Laminas Filter to preprocess input in the `prepareForValidation()` method of your Form Request. For example, sanitize and normalize data before Laravel’s validator runs. This keeps validation rules focused on business logic while offloading data hygiene to Laminas. Example: `$this->merge([‘input’ => (new FilterChain())->setFilters([...])->filter($this->all())]);`
- Are there alternatives to laminas/laminas-filter for Laravel?
- Yes. For basic filtering, Laravel’s Str helpers or `Illuminate\Support\Str` suffice. For advanced use cases, consider `symfony/filter` (part of Symfony Components) or `league/pipe` for pipeline-based transformations. If you’re already using Laminas components, this package integrates seamlessly, but evaluate whether its features align with your project’s needs before adding a dependency.
