Features

Parsedown is an efficient, modern PHP implementation of Markdown syntax originally developed by John Gruber.

• No Dependencies
• Super Fast
• Extensible
• GitHub flavored

Why Parsedown? It's faster, more consistent and is being actively developed. https://github.com/erusev/parsedown https://github.com/parsedown/parsedown

Parsedown passes most CommonMark tests. The tests that fail are more unusual cases. However, as CommonMark continues to evolve, compliance should improve.
