league/commonmark is a highly-extensible PHP Markdown parser that fully supports the CommonMark and GitHub-Flavored Markdown specifications. It converts Markdown to HTML via an easy-to-use converter API with built-in extensions, security options, and support for custom syntax and renderers.

Use cases

• convert markdown to html in php
• parse user-submitted markdown safely
• render github-flavored markdown
• add custom markdown syntax to a php app
• render markdown in a cms or framework
• generate html from markdown documentation files

When to choose

• you need a spec-compliant CommonMark or GFM parser in PHP
• you need to sanitize untrusted markdown input with html stripping and unsafe link blocking
• you want to extend markdown with custom syntax, renderers, or extensions
• you need integrations with popular PHP frameworks and CMSes

When to avoid

• your project is not written in PHP
• you only need a lightweight regex-based markdown converter without spec compliance
• you need to parse non-UTF-8/ASCII encodings without converting first
