## What it is
A small PHP library that maps a line of code to the function or method it belongs to. It is primarily used as a dependency of PHPUnit and is now a low-maintenance project.

## Use cases
- find which function a line of php code belongs to
- map stack trace line numbers to methods
- resolve code location for error reporting in php
- determine enclosing method for a given file line
- support test failure reporting in phpunit

## When to choose
- you need line-to-function mapping in a PHP project
- you are building PHP tooling that reports code locations
- you need it as a PHPUnit dependency

## When to avoid
- you need active development or new features
- you work outside the PHP ecosystem
- you need full static analysis rather than simple line lookup

## Facets
- artifact type: library
- maturity: maintenance
- function: parser, developer-tools
- domain: developer-tools, testing, parsers
- platform: php, cli
- tags: php-library, code-introspection, phpunit-dependency, composer-package
