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. ### Community Maintainers ![](https://www.gravatar.com/avatar/9d40665a360eef88be50ddf2fad41317ab6378c4ef77a767f88050ab22bef402?d=identicon)[royopa](/maintainers/royopa) --- Top Contributors [![royopa](https://avatars.githubusercontent.com/u/442991?v=4)](https://github.com/royopa "royopa (28 commits)")[![pmtarantino](https://avatars.githubusercontent.com/u/2265645?v=4)](https://github.com/pmtarantino "pmtarantino (3 commits)") ### Embed Badge ![Health badge](/badges/royopa-mat-lab-php/health.svg) ``` [![Health](https://phpackages.com/badges/royopa-mat-lab-php/health.svg)](https://phpackages.com/packages/royopa-mat-lab-php) ``` ### Alternatives [lizhichao/one-sm 国密sm3 1891.5M8](/packages/lizhichao-one-sm)[protonemedia/laravel-task-runner Write Shell scripts like Blade Components and run them locally or on a remote server 1335.5k1](/packages/protonemedia-laravel-task-runner)[xiaodi/think-pinyin ThinkPHP 中文转拼音扩展包 344.8k](/packages/xiaodi-think-pinyin) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
