Generated differences can be rendered in all of the standard formats including: - Unified - Context - Inline HTML - Side by Side HTML The logic behind the core of the diff engine (ie, the sequence matcher) is primarily based on the Python difflib package. The reason for doing so is primarily because of its high degree of accuracy. Example Use ----------- [](#example-use) A quick usage example can be found in the example/ directory and under example.php. [![Example Image](https://github.com/jblond/php-diff/raw/master/readme.png "Example")](https://github.com/jblond/php-diff/raw/master/readme.png) Requirements ------------ [](#requirements) PHP Multibyte String Merge files using jQuery ------------------------ [](#merge-files-using-jquery) Xiphe has build a jQuery plugin with that you can merge the compared files. Have a look at [jQuery-Merge-for-php-diff](https://github.com/Xiphe/jQuery-Merge-for-php-diff).

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 ~169 days Total 3 Last Release 2962d ago ### Community Maintainers ![](https://avatars.githubusercontent.com/u/2509658?v=4)[Stupid Dev](/maintainers/vuthaihoc)[@vuthaihoc](https://github.com/vuthaihoc) --- Top Contributors [![JBlond](https://avatars.githubusercontent.com/u/2391810?v=4)](https://github.com/JBlond "JBlond (55 commits)")[![chrisboulton](https://avatars.githubusercontent.com/u/98472?v=4)](https://github.com/chrisboulton "chrisboulton (6 commits)")[![kelunik](https://avatars.githubusercontent.com/u/2743004?v=4)](https://github.com/kelunik "kelunik (2 commits)")[![vuthaihoc](https://avatars.githubusercontent.com/u/2509658?v=4)](https://github.com/vuthaihoc "vuthaihoc (2 commits)")[![joshfraser](https://avatars.githubusercontent.com/u/982234?v=4)](https://github.com/joshfraser "joshfraser (1 commits)")[![dgarrett](https://avatars.githubusercontent.com/u/1408738?v=4)](https://github.com/dgarrett "dgarrett (1 commits)")[![kriss0r](https://avatars.githubusercontent.com/u/476914?v=4)](https://github.com/kriss0r "kriss0r (1 commits)")[![maxxer](https://avatars.githubusercontent.com/u/240201?v=4)](https://github.com/maxxer "maxxer (1 commits)")[![Xiphe](https://avatars.githubusercontent.com/u/911218?v=4)](https://github.com/Xiphe "Xiphe (1 commits)")[![jensklose](https://avatars.githubusercontent.com/u/1216675?v=4)](https://github.com/jensklose "jensklose (1 commits)") ### Embed Badge ![Health badge](/badges/123dok-php-diff/health.svg) ``` [![Health](https://phpackages.com/badges/123dok-php-diff/health.svg)](https://phpackages.com/packages/123dok-php-diff) ``` ### Alternatives [nikolaposa/version Value Object that represents a SemVer-compliant version number. 1406.4M16](/packages/nikolaposa-version)[whatthejeff/nyancat-scoreboard Nyan Cat Scoreboard 19985.0k4](/packages/whatthejeff-nyancat-scoreboard)[symfony/ux-swup Swup integration for Symfony 33147.8k1](/packages/symfony-ux-swup) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
