## What it is
cebe/markdown is a fast, highly extensible Markdown parser library for PHP that converts Markdown to HTML. It ships as a set of PHP classes, each representing a Markdown flavor (traditional Markdown, GitHub-flavored Markdown, and partially Markdown Extra), plus a command-line tool for converting Markdown files to HTML. It exposes an AST-based internal representation so new language elements can be added by adding methods rather than writing fragile regular expressions.

## Use cases
- convert markdown files to html from the command line
- render user-submitted markdown comments in a php web app
- parse github-flavored markdown in php
- extend markdown with custom syntax elements
- read markdown structure via an abstract syntax tree
- power documentation rendering for a php framework

## When to choose
- you need a fast, well-tested Markdown-to-HTML parser in PHP
- you need GitHub-flavored Markdown support
- you want to extend Markdown with custom elements via an AST instead of regex hacks
- you need a simple CLI tool for batch Markdown conversion

## When to avoid
- you need full Markdown Extra support, which is incomplete
- you need a parser in a language other than PHP
- you need SmartyPants or other planned-but-unimplemented flavors
- you need a library under very active development - the latest release is from 2022
