Data Mapping ------------ [](#data-mapping) You can map a source array to a target array and even apply filters and post converters. This can help you when programming Import-Scripts with large datasets from one format to another. ``` namespace Gressus\Tools; require('../autoload.php'); $dataMapperService = new DataMapperService( array( 'Identifier' => 'id', 'Group + Name' => new Mapper\Concat(array( 'group', new Mapper\FirstNotEmpty(array('full_name','name'))) ), 'Counter' => new Mapper\Counter(), 'FirstChar' => new Mapper\FirstChar('name'), 'Name' => new Mapper\FirstNotEmpty(array('full_name','name')), 'Hash' => new Mapper\All(), 'Weapons' => new Mapper\ArrayPath('special/weapons'), ), array( new Converter\Serialize('Hash'), new Converter\Md5('Hash'), new Converter\Implode('Weapons'), ), array( array('score',new Filter\GreaterThanFilter(0)), ), array( array('Counter',new Filter\GreaterThanFilter(1)), ) );

I originally started the development of these Tools working in the nice office at TUDOCK. ### Health Score 47 — FairBetter than 94% of packages Maintenance61 Regular maintenance activity Popularity32 Limited adoption so far Community14 Small or concentrated contributor base Maturity68 Established project with proven stability Bus Factor1 Top contributor holds 60% of commits — single point of failure 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 ~178 days Recently: every ~453 days Total 21 Last Release 249d ago PHP version history (2 changes)1.0.0PHP 5.4.0 1.0.1PHP >= 5.4.0 ### Community Maintainers ![](https://www.gravatar.com/avatar/82cca472fdb2594150c48063464e92fb3f469c5f805418083d36d4bf2d492c40?d=identicon)[gressus](/maintainers/gressus) --- Top Contributors [![bazen](https://avatars.githubusercontent.com/u/3831024?v=4)](https://github.com/bazen "bazen (6 commits)")[![mdoelker](https://avatars.githubusercontent.com/u/2145319?v=4)](https://github.com/mdoelker "mdoelker (2 commits)")[![mguettler](https://avatars.githubusercontent.com/u/821149?v=4)](https://github.com/mguettler "mguettler (1 commits)")[![tobiasthaden](https://avatars.githubusercontent.com/u/2782913?v=4)](https://github.com/tobiasthaden "tobiasthaden (1 commits)") ### Embed Badge ![Health badge](/badges/gressus-tools/health.svg) ``` [![Health](https://phpackages.com/badges/gressus-tools/health.svg)](https://phpackages.com/packages/gressus-tools) ``` ### Alternatives [powder96/numbers.php Advanced Mathematics Library for PHP (port of Numbers.js) 15844.0k1](/packages/powder96-numbersphp) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
