## What it is
A PHP library that parses Markdown and Markdown Extra syntax and converts it to HTML, derived from John Gruber's original Markdown.pl. It is installed via Composer and used by calling static transform methods or configurable parser instances.

## Use cases
- convert markdown text to html in php
- render user-submitted markdown comments
- parse markdown with tables and footnotes via markdown extra
- add markdown rendering to a php blog or cms
- transform markdown files into web pages

## When to choose
- you need a battle-tested, faithful Markdown implementation in PHP
- you need Markdown Extra features like tables, footnotes, and definition lists
- your project already uses Composer and PSR-4 autoloading

## When to avoid
- you need CommonMark strict compliance or GFM extensions like task lists
- you are not working in PHP
- you need very high-performance parsing of huge documents

## Facets
- artifact type: library
- maturity: maintenance
- function: parser, markdown, templating
- domain: web-development, parsers, documentation
- platform: php
- tags: markdown-to-html, markdown-extra, composer, web-server
