## What it is
The official PHP port of the Hamcrest matcher library, providing a fluent set of matchers for writing expressive assertions in tests. It follows the original Java API closely and integrates with PHPUnit via MatcherAssert and global proxy functions.

## Use cases
- write readable assertions in phpunit tests
- match values with expressive matchers like equalTo or containsString
- combine matchers with both/andAlso and either/orElse
- avoid risky test warnings by counting hamcrest assertions
- port java hamcrest test styles to php

## When to choose
- you want declarative, composable matchers instead of plain assert calls
- you are already using PHPUnit and want richer assertion expressiveness
- you are porting Hamcrest-based tests from Java or other languages to PHP

## When to avoid
- you prefer PHPUnit's built-in assertions without extra dependencies
- you need collection matchers that have not been ported yet
- your project does not use PHP

## Facets
- artifact type: library
- maturity: stable
- function: testing, mocking
- domain: testing, developer-tools
- platform: php
