Small usage example ------------------- [](#small-usage-example) ``` $f = new Particle\Filter\Filter; $f->values(['user.first_name', 'user.last_name'])->trim()->lower()->upperFirst(); $f->value('newsletter')->bool(); $f->value('created_at')->defaults(date('Y-m-d')); $f->all()->removeNull(); $result = $f->filter([ 'user' => [ 'first_name' => ' JOHN ', 'middle_name' => null, 'last_name' => ' DOE ', ], 'newsletter' => 'yes', 'referral' => null, ]); var_dump($result); /** * array(3) { * ["user"]=> array(2) { * ["first_name"]=> string(4) "John" * ["last_name"]=> string(3) "Doe" * } * ["newsletter"]=> bool(true) * ["created_at"]=> string(10) "2015-12-10" * } */ ``` Functional features ------------------- [](#functional-features) - Filter an array of values - Get a cleaned array after filtering - [A large set of available filters](http://filter.particle-php.com/en/latest/filter-rules/) - Ability to set default values if nothing is provided - Ability to filter nested, repeated arrays - Ability to remove (empty) values - Ability to extend the filter to add your own custom filter rules Non functional features ----------------------- [](#non-functional-features) - Easy to write (IDE auto-completion for easy development) - Easy to read (improves peer review) - Fully documented: [filter.particle-php.com](http://filter.particle-php.com) - Fully tested: [Scrutinizer](https://scrutinizer-ci.com/g/particle-php/Filter/?branch=master) - Zero dependencies === Find more information and advanced usage examples at [filter.particle-php.com](http://filter.particle-php.com) ### Health Score 45 — FairBetter than 91% of packages Maintenance19 Infrequent updates — may be unmaintained Popularity52 Moderate usage in the ecosystem Community28 Small or concentrated contributor base Maturity67 Established project with proven stability Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio. Uses a 2-year decay window. **Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores. **Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement. **Maturity (30%)** — Project age, version count, PHP version support, and release stability. ### Release Activity Cadence Every ~96 days Recently: every ~284 days Total 17 Last Release 2509d ago Major Versions v0.6.0 → v1.0.02015-06-26 PHP version history (2 changes)v0.1.0PHP >=5.3.2 v0.3.0PHP >=5.4 ### Community Maintainers ![](https://www.gravatar.com/avatar/6169c8b4657a79f3a96b4f167abc794d76402db6e4c0ad4bfe0c9b71fa8b2ef1?d=identicon)[berry\_\_](/maintainers/berry__) ![](https://www.gravatar.com/avatar/8517df511923178ac5c36f913626d23a678563d2af6219bd77c46f3b5466c794?d=identicon)[RickvdStaaij](/maintainers/RickvdStaaij) --- Top Contributors [![localheinz](https://avatars.githubusercontent.com/u/605483?v=4)](https://github.com/localheinz "localheinz (12 commits)")[![skoop](https://avatars.githubusercontent.com/u/90003?v=4)](https://github.com/skoop "skoop (11 commits)")[![renatomefi](https://avatars.githubusercontent.com/u/823634?v=4)](https://github.com/renatomefi "renatomefi (6 commits)")[![jhuet](https://avatars.githubusercontent.com/u/372409?v=4)](https://github.com/jhuet "jhuet (5 commits)")[![berry-langerak](https://avatars.githubusercontent.com/u/203825?v=4)](https://github.com/berry-langerak "berry-langerak (3 commits)")[![Finesse](https://avatars.githubusercontent.com/u/9006227?v=4)](https://github.com/Finesse "Finesse (1 commits)")[![rick-nu](https://avatars.githubusercontent.com/u/6495166?v=4)](https://github.com/rick-nu "rick-nu (1 commits)")[![albertcansado](https://avatars.githubusercontent.com/u/4248492?v=4)](https://github.com/albertcansado "albertcansado (1 commits)") --- Tags filterfiltering ### Code Quality TestsPHPUnit Code StylePHP\_CodeSniffer ### Embed Badge ![Health badge](/badges/particle-filter/health.svg) ``` [![Health](https://phpackages.com/badges/particle-filter/health.svg)](https://phpackages.com/packages/particle-filter) ``` ### Alternatives [clue/stream-filter A simple and modern approach to stream filtering in PHP 1.7k276.5M9](/packages/clue-stream-filter)[laminas/laminas-filter Programmatically filter and normalize data and files 9530.3M181](/packages/laminas-laminas-filter)[htmlawed/htmlawed Official htmLawed PHP library for HTML filtering 481.2M15](/packages/htmlawed-htmlawed)[bukashk0zzz/filter-bundle Symfony filter bundle. 24459.9k1](/packages/bukashk0zzz-filter-bundle)[messere/php-value-mask extract subset of array / object values 1147.4k1](/packages/messere-php-value-mask)[kalfheim/sanitizer Data sanitizer for PHP with built-in Laravel support. 1523.8k](/packages/kalfheim-sanitizer) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
