``` if you want an environment to run or test it, you can build and install dependences like this ``` docker build --build-arg PHP_VERSION=8.4-cli -t not-empty/ulid-php-lib:php84 -f contrib/Dockerfile . ``` Access the container ``` docker run -v ${PWD}/:/var/www/html -it not-empty/ulid-php-lib:php84 bash ``` Verify if all dependencies is installed ``` composer install --no-dev --prefer-dist ``` and run ``` php sample/ulid-sample.php ``` ### Development [](#development) Want to contribute? Great! The project using a simple code. Make a change in your file and be careful with your updates! **Any new code will only be accepted with all validations.** To ensure that the entire project is fine: First you need to building a correct environment to install all dependences ``` docker build --build-arg PHP_VERSION=8.4-cli -t not-empty/ulid-php-lib:php84 -f contrib/Dockerfile . ``` Access the container ``` docker run --name ulid-php-lib -v ${PWD}/:/var/www/html -it not-empty/ulid-php-lib:php84 bash ``` Install all dependences ``` composer install --dev --prefer-dist ``` Run all validations ``` composer check ``` **Not Empty Foundation - Free codes, full minds** ### Health Score 51 — FairBetter than 96% of packages Maintenance79 Regular maintenance activity Popularity31 Limited adoption so far Community16 Small or concentrated contributor base Maturity66 Established project with proven stability Bus Factor1 Top contributor holds 73.8% 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 ~104 days Recently: every ~206 days Total 9 Last Release 112d ago Major Versions 3.0.0 → 5.0.02023-10-25 2.0.0 → 4.0.02023-10-25 4.0.0 → 6.0.02023-10-25 6.0.0 → 7.0.02023-11-26 7.0.0 → 8.0.02025-12-17 PHP version history (8 changes)1.0.0PHP ^7.1 3.0.0PHP ^7.3 5.0.0PHP ^8.1 2.0.0PHP ^7.2 4.0.0PHP ^7.4 6.0.0PHP ^8.2 7.0.0PHP ^8.3 8.0.0PHP ^8.4 ### Community Maintainers ![](https://www.gravatar.com/avatar/3a8e537dba9018eff457d477dba8f79158989b41ca86bd74d1c4a1186c158caa?d=identicon)[kiwfy](/maintainers/kiwfy) --- Top Contributors [![leodisarli](https://avatars.githubusercontent.com/u/1638455?v=4)](https://github.com/leodisarli "leodisarli (31 commits)")[![espositovitor](https://avatars.githubusercontent.com/u/26362498?v=4)](https://github.com/espositovitor "espositovitor (7 commits)")[![RafaJEstabile](https://avatars.githubusercontent.com/u/149419100?v=4)](https://github.com/RafaJEstabile "RafaJEstabile (2 commits)")[![brunavitoria](https://avatars.githubusercontent.com/u/43785466?v=4)](https://github.com/brunavitoria "brunavitoria (1 commits)")[![JhonatanEstabile](https://avatars.githubusercontent.com/u/40630775?v=4)](https://github.com/JhonatanEstabile "JhonatanEstabile (1 commits)") ### Code Quality TestsPHPUnit Static AnalysisPHPStan Code StylePHP\_CodeSniffer Type Coverage Yes ### Embed Badge ![Health badge](/badges/kiwfy-ulid-php/health.svg) ``` [![Health](https://phpackages.com/badges/kiwfy-ulid-php/health.svg)](https://phpackages.com/packages/kiwfy-ulid-php) ``` ### Alternatives [joy2362/php-time-zone A simple package that provide list of all timezone that php support 162.0k](/packages/joy2362-php-time-zone)[hashandsalt/kirby3-seo Kirby 3 - SEO tools 103.8k](/packages/hashandsalt-kirby3-seo) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
