It's the best format for PHP Symfony applications: - [Modernize Symfony Configs](https://getrector.com/blog/modernize-symfony-configs) - [10 Cool Features You Get after switching from YAML to PHP Configs](https://tomasvotruba.com/blog/2020/07/16/10-cool-features-you-get-after-switching-from-yaml-to-php-configs/) - [How to Switch from YAML/XML Configs to PHP Today with Symplify](https://tomasvotruba.com/blog/2020/07/27/how-to-switch-from-yaml-xml-configs-to-php-today-with-migrify/) Install ------- [](#install) ``` composer require symplify/config-transformer --dev ``` Usage ----- [](#usage) By default, the command uses `/config` directory to transform all files in it. At first, run it with `--dry-run` to see what files *would be* transformed: ``` vendor/bin/config-transformer --dry-run ``` Do you want to convert single file or directory at a time? Specify the paths as arguments: ``` vendor/bin/config-transformer config/parameters.yml --dry-run ``` Are you ready to go? Remove `--dry-run`: ``` vendor/bin/config-transformer ``` The input files are deleted automatically. ### Skip Routes at First [](#skip-routes-at-first) It's typical to upgrade first services and then routes as follow up PR. To do that, use `--skip-routes` option: ``` vendor/bin/config-transformer --skip-routes ``` ### Health Score 58 — FairBetter than 98% of packages Maintenance59 Moderate activity, may be stable Popularity59 Moderate usage in the ecosystem Community33 Small or concentrated contributor base Maturity69 Established project with proven stability Bus Factor1 Top contributor holds 89% 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 ~5 days Recently: every ~44 days Total 381 Last Release 307d ago Major Versions 0.4.2 → 9.0.0-BETA22020-11-24 9.4.70 → 10.0.0-beta12021-11-02 10.3.3 → 11.0.12022-06-13 11.2.3.72 → 12.0.02023-01-31 PHP version history (7 changes)v0.3.2PHP ^7.2 v0.3.32PHP ^7.2|^8.0 0.3.34PHP >=7.2 9.0.0-rc1PHP >=7.3 v9.3.22PHP >=7.1 v9.3.25PHP >=8.0 11.1.25PHP >=8.1 ### Community Maintainers ![](https://avatars.githubusercontent.com/u/924196?v=4)[Tomas Votruba](/maintainers/TomasVotruba)[@TomasVotruba](https://github.com/TomasVotruba) --- Top Contributors [![actions-user](https://avatars.githubusercontent.com/u/65916846?v=4)](https://github.com/actions-user "actions-user (1847 commits)")[![TomasVotruba](https://avatars.githubusercontent.com/u/924196?v=4)](https://github.com/TomasVotruba "TomasVotruba (193 commits)")[![samsonasik](https://avatars.githubusercontent.com/u/459648?v=4)](https://github.com/samsonasik "samsonasik (20 commits)")[![ThomasLandauer](https://avatars.githubusercontent.com/u/1054469?v=4)](https://github.com/ThomasLandauer "ThomasLandauer (3 commits)")[![localheinz](https://avatars.githubusercontent.com/u/605483?v=4)](https://github.com/localheinz "localheinz (3 commits)")[![sad270](https://avatars.githubusercontent.com/u/5607440?v=4)](https://github.com/sad270 "sad270 (2 commits)")[![dannyvankooten](https://avatars.githubusercontent.com/u/885856?v=4)](https://github.com/dannyvankooten "dannyvankooten (2 commits)")[![GromNaN](https://avatars.githubusercontent.com/u/400034?v=4)](https://github.com/GromNaN "GromNaN (2 commits)")[![b1rdex](https://avatars.githubusercontent.com/u/312855?v=4)](https://github.com/b1rdex "b1rdex (1 commits)")[![leoloso](https://avatars.githubusercontent.com/u/1981996?v=4)](https://github.com/leoloso "leoloso (1 commits)")[![PhilETaylor](https://avatars.githubusercontent.com/u/400092?v=4)](https://github.com/PhilETaylor "PhilETaylor (1 commits)")[![COil](https://avatars.githubusercontent.com/u/177844?v=4)](https://github.com/COil "COil (1 commits)") --- Tags converterphpsymfonyxmlyaml ### Embed Badge ![Health badge](/badges/symplify-config-transformer/health.svg) ``` [![Health](https://phpackages.com/badges/symplify-config-transformer/health.svg)](https://phpackages.com/packages/symplify-config-transformer) ``` ### Alternatives [masterminds/html5 An HTML5 parser and serializer. 1.8k242.8M229](/packages/masterminds-html5)[sabberworm/php-css-parser Parser for CSS Files written in PHP 1.8k191.2M65](/packages/sabberworm-php-css-parser)[jms/metadata Class/method/property metadata management in PHP 1.8k152.8M88](/packages/jms-metadata)[jms/serializer-bundle Allows you to easily serialize, and deserialize data of any complexity 1.8k89.3M627](/packages/jms-serializer-bundle)[hassankhan/config Lightweight configuration file loader that supports PHP, INI, XML, JSON, and YAML files 97513.5M170](/packages/hassankhan-config)[meyfa/php-svg Read, edit, write, and render SVG files with PHP 54613.9M42](/packages/meyfa-php-svg) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
