This library is a fork of [sebastian/diff](https://github.com/sebastianbergmann/diff): While the original diff implementation has not notably changed, new features were added: - Configurable limit for lines of context around the modified lines - Plain PHP templates for displaying diffs in: - Plain text - Colored POSIX console output - HTML - Github flavoured Markdown - Modify existing templates or create your own - Line numbering based on the "before" string - `Upstream` formatter for maintaining compatibility with `sebastian/diff` — and to keep the original tests around --- - [nochso/diff](#nochsodiff) - [Installation](#installation) - [Usage](#usage) Installation ============ [](#installation) ``` composer require nochso/diff ``` Usage ===== [](#usage) Start with creating a `Diff` object by passing two strings to `Diff::create()`: ``` $diff = \nochso\Diff\Diff::create('foo', 'bar'); ``` The Diff object contains a list of `DiffLine` objects, consisting of text, a line number and the type of diff operation. ``` foreach ($diff->getDiffLines() as $line) { if ($line->isRemoval()) { echo 'Line ' . $line->getLineNumberFrom() . " was removed:\n"; echo $line->getText() . "\n"; } } ``` Most of the time you'll want to display the diff somewhere. You can pass a Diff instance to anything that implements the `Formatter` interface: ``` $formatter = new \nochso\Diff\Format\Template\Text(); echo $formatter->format($diff); ``` Output: ``` 1: -foo : +bar ``` How about two lines of context and Github flavoured Markdown? ``` $context = new ContextDiff(); $context->setMaxContext(2); $diff = Diff::create($from, $to, $context); $gfm = new \nochso\Diff\Format\Template\GithubMarkdown(); echo $gfm->format($diff); ``` ``` ```diff 2: pariatur ground round 3: dolore meatloaf nisi -4: shoulder. 5: Consequat rump spare -6: ribs ham hock shank. 7: Magna esse nisi 8: frankfurter picanha ``` ``` As you can see, when creating a Diff you can pass a ContextDiff object to change the default behaviour. ### Health Score 30 — LowBetter than 64% of packages Maintenance13 Infrequent updates — may be unmaintained Popularity16 Limited adoption so far Community18 Small or concentrated contributor base Maturity63 Established project with proven stability Bus Factor1 Top contributor holds 57.5% 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 ~176 days Recently: every ~163 days Total 7 Last Release 3635d ago Major Versions 1.4.1 → 2.0.02016-05-31 PHP version history (2 changes)1.0.0PHP >=5.3.3 2.0.0PHP >=5.6.0 ### Community Maintainers ![](https://avatars.githubusercontent.com/u/6887618?v=4)[Marcel Voigt](/maintainers/nochso)[@nochso](https://github.com/nochso) --- Top Contributors [![nochso](https://avatars.githubusercontent.com/u/6887618?v=4)](https://github.com/nochso "nochso (88 commits)")[![sebastianbergmann](https://avatars.githubusercontent.com/u/25218?v=4)](https://github.com/sebastianbergmann "sebastianbergmann (44 commits)")[![whatthejeff](https://avatars.githubusercontent.com/u/306525?v=4)](https://github.com/whatthejeff "whatthejeff (7 commits)")[![nafigator](https://avatars.githubusercontent.com/u/1971423?v=4)](https://github.com/nafigator "nafigator (3 commits)")[![GrahamCampbell](https://avatars.githubusercontent.com/u/2829600?v=4)](https://github.com/GrahamCampbell "GrahamCampbell (3 commits)")[![djmattyg007](https://avatars.githubusercontent.com/u/489338?v=4)](https://github.com/djmattyg007 "djmattyg007 (3 commits)")[![pscheit](https://avatars.githubusercontent.com/u/488189?v=4)](https://github.com/pscheit "pscheit (2 commits)")[![mimrock](https://avatars.githubusercontent.com/u/779206?v=4)](https://github.com/mimrock "mimrock (1 commits)")[![keradus](https://avatars.githubusercontent.com/u/2716794?v=4)](https://github.com/keradus "keradus (1 commits)")[![henriquemoody](https://avatars.githubusercontent.com/u/154023?v=4)](https://github.com/henriquemoody "henriquemoody (1 commits)") --- Tags difflcs ### Code Quality TestsPHPUnit ### Embed Badge ![Health badge](/badges/nochso-diff/health.svg) ``` [![Health](https://phpackages.com/badges/nochso-diff/health.svg)](https://phpackages.com/packages/nochso-diff) ``` ### Alternatives [jfcherng/php-diff A comprehensive library for generating differences between two strings in multiple formats (unified, side by side HTML etc). 4705.1M51](/packages/jfcherng-php-diff)[caxy/php-htmldiff A library for comparing two HTML files/snippets and highlighting the differences using simple HTML. 21520.9M15](/packages/caxy-php-htmldiff)[localheinz/diff Fork of sebastian/diff for use with ergebnis/composer-normalize 4637.0M5](/packages/localheinz-diff)[mkalkbrenner/php-htmldiff-advanced An add-on for the php-htmldiff library for comparing two HTML files/snippets and highlighting the differences using simple HTML. 3517.8M1](/packages/mkalkbrenner-php-htmldiff-advanced)[jbzoo/composer-diff See what has changed after a composer update. 53888.9k1](/packages/jbzoo-composer-diff)[lolli42/finediff PHP implementation of a Fine granularity Diff engine 138.8M3](/packages/lolli42-finediff) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
