## What it is
PsySH is a runtime developer console, interactive debugger, and REPL for PHP. It provides an interactive shell with tab completion, inline documentation, source inspection, and can be dropped into code as a debugger via eval(\Psy\sh()).

## Use cases
- interactive php repl
- debug php code interactively
- inspect php classes and objects from a shell
- look up php function documentation from the terminal
- drop a breakpoint into php code to explore state
- test php snippets without writing a script

## When to choose
- you want to experiment with PHP code interactively
- you need an inline debugger in a PHP application
- you want quick introspection of classes, functions, and variables
- you use frameworks like Laravel, Drupal, or WordPress that build on it

## When to avoid
- you need a full IDE debugger with step-through and breakpoints UI
- you are working in a language other than PHP
- you need automated testing rather than interactive exploration

## Facets
- artifact type: cli-tool
- maturity: active
- function: cli, developer-tools, interpreter, documentation
- domain: developer-tools, programming-languages
- platform: cli, php, cross-platform, windows
- tags: repl, interactive-debugger, php-shell, introspection, tinker, command-line, macos, linux
