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 93% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity51 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.
