$json = \ByJG\Serializer\Serialize::from($object) ->toJson(); ``` ### Copy properties between objects [](#copy-properties-between-objects) ``` $source = ["id" => 1, "name" => "John"]; $target = new User(); \ByJG\Serializer\ObjectCopy::copy($source, $target); ``` ### Create a copyable object [](#create-a-copyable-object) ``` class User implements \ByJG\Serializer\ObjectCopyInterface { use \ByJG\Serializer\ObjectCopyTrait; public $id; public $name; // Automatically inherits copyFrom() and copyTo() methods } ``` Documentation ------------- [](#documentation) ### Core Components [](#core-components) ComponentDescriptionLink**Serialize**Core component for converting objects between formats[Documentation](docs/serialize.md)**ObjectCopy**Final utility class for copying properties between objects[Documentation](docs/objectcopy.md)**ObjectCopyTrait**Trait implementing copyable object functionality[Documentation](docs/objectcopytrait.md)**ObjectCopyInterface**Interface for implementing copyable objects[Documentation](docs/objectcopyinterface.md)**BaseModel**Abstract base class with object copying functionality[Documentation](docs/basemodel.md)**DirectTransform**Basic property handler for direct transformations in ObjectCopy[Documentation](docs/directtransform.md)### Guides [](#guides) - **[Formatters](docs/formatters.md)** - JSON, XML, YAML, CSV, and Plain Text output formatting - **[Property Handlers](docs/propertyhandlers.md)** - Transform property names and values during copying - **[Advanced Usage](docs/advanced-usage.md)** - Performance optimization, security, and complex patterns - **[Integration Examples](docs/integration-examples.md)** - Framework integration (Symfony, Laravel, Doctrine, etc.) - **[ByJG Ecosystem](docs/byjg-ecosystem.md)** - How Serializer integrates with other ByJG components - **[Troubleshooting](docs/troubleshooting.md)** - Common issues and solutions Installation ------------ [](#installation) ``` composer require "byjg/serializer" ``` Testing ------- [](#testing) ``` ./vendor/bin/phpunit ``` Dependencies ------------ [](#dependencies) ``` flowchart TD byjg/serializer --> ext-json byjg/serializer --> symfony/yaml byjg/serializer --> ext-simplexml ``` Loading --- [Open source ByJG](http://opensource.byjg.com) ### Health Score 60 — FairBetter than 98% of packages Maintenance78 Regular maintenance activity Popularity39 Limited adoption so far Community15 Small or concentrated contributor base Maturity89 Battle-tested with a long release history Bus Factor1 Top contributor holds 100% 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 ~223 days Recently: every ~122 days Total 17 Last Release 126d ago Major Versions 1.0.7 → 4.9.02023-05-21 4.9.2 → 5.0.x-dev2024-10-27 5.0.0 → 6.0.02025-11-26 PHP version history (6 changes)1.0.0PHP >=5.4.0 1.0.3PHP >=5.5 4.9.0PHP >=5.6 4.9.1PHP >=7.4 5.0.x-devPHP >=8.1 <8.4 6.0.0PHP >=8.3 <8.6 ### Community Maintainers ![](https://avatars.githubusercontent.com/u/981924?v=4)[Joao Gilberto Magalhaes](/maintainers/byjg)[@byjg](https://github.com/byjg) --- Top Contributors [![byjg](https://avatars.githubusercontent.com/u/981924?v=4)](https://github.com/byjg "byjg (136 commits)") --- Tags bindingjsonphpserializerxml ### Code Quality TestsPHPUnit Static AnalysisPsalm Type Coverage Yes ### Embed Badge ![Health badge](/badges/byjg-serializer/health.svg) ``` [![Health](https://phpackages.com/badges/byjg-serializer/health.svg)](https://phpackages.com/packages/byjg-serializer) ``` ### Alternatives [craftcms/cms Craft CMS 3.6k3.6M3.1k](/packages/craftcms-cms)[tempest/framework The PHP framework that gets out of your way. 2.2k34.4k15](/packages/tempest-framework)[rcsofttech/audit-trail-bundle Enterprise-grade, high-performance Symfony audit trail bundle.
