Parsedown is a parser for Markdown. It parses Markdown text the way people do. First, it divides texts into blocks. Then it looks at how these blocks start and how they relate to each other. Finally, it looks for special characters to identify inline elements. As a result, Parsedown is (super) fast, consistent and clean.
Include Parsedown.php or install the composer package.
$text = 'Hello **Parsedown**!';
$result = Parsedown::instance()->parse($text);
echo $result; # prints: <p>Hello <strong>Parsedown</strong>!</p>
