Markdown downmark

A speedy Markdown parser for PHP applications.

Latest Version on Packagist Tests Total Downloads

This is a super lightweight Markdown parser for PHP projects and applications. It has a rather verbose but powerful extension API for adding custom blocks and inline elements.


At the moment, Downmark has support for the following Markdown blocks:

  • Headings (h1 - h6)
  • Blockquotes (multi-line support)
  • Single-level unordered and ordered lists
  • Backtick-delimited code blocks

It also has support for the following inline elements:

  • Links
  • Images
  • Bold, italic and strikethrough
  • Inline code


You can install the package via Composer:

composer require ryangjchandler/downmark


To parse a string of Markdown and compile it to HTML, do the following:

use Downmark\Downmark;

$parser = Downmark::create();

$html = $parser->parse('**Hello!**');

Block extensions

To create a custom block-level extensions, you first need to register it with the parser:

use Downmark\Blocks\Block;

    ->block("/::: (.*)/", function (array $matches): Block {


The Downmark::block() methods accepts 2 arguments. The first is a regular expression, used by the parser to find the start of your block. The second is a Closure that should return an instance of Downmark\Blocks\Block.

You can create an object that extends the Downmark\Blocks\Block class. This class only requires you to implement a single public toHtml(): string method.

' . $this->content . '
'; } }">
use Downmark\Blocks\Block;

class NoticeBlock extends Block
    public function __construct(
        protected ?string $content = '',
    ) {}

    public function toHtml(): string
        return '
' . $this->content . '
; } }

Inside of the extension callback, you can return an instance of NoticeBlock.

    ->block("/::: (.*)/", function (array $matches): Block {
        return new NoticeBlock($matches[1]);

When the parser compiles your Markdown, it will check if this block matches and execute the callback function.

Note: Documentation on building multi-line blocks coming soon... If you're super eager, source-dive the tests to find out how it works.

Inline extensions

Downmark also provides an API for extending Markdown with custom inline elements. The example below extends Downmark to support a "mention" syntax that generates links to Twitter profiles.

%s', $matches[1], $matches[0]); });">
    // Look for any inline text that matches a single `@` character followed by 1 to 15 alphanumeric (incl. underscore) characters.
    ->inline("/@([A-Za-z0-9_]{1,15})(?!\w)/", function (array $matches): string {
        return sprintf('%s', $matches[1], $matches[0]);

The callback function should return a string. This will be used to replace the regular-expression match.


A preprocessor is any class that implements the Downmark\Interfaces\Preprocessor interface.

use Downmark\Interfaces\Preprocessor;
use Downmark\Blocks\Block;
use Downmark\Blocks\Paragraph;

class RickRoller implements Preprocessor
    public function preprocess(Block $block): Block
        if (! $block instanceof Paragraph) {
            return $block;

        $block->content = 'Rick rolled!';

        return $block;

The RickRoller class above will receive each Block in the document. It can then modify the block, return a new block or leave it as it is. This preprocessor will replace the content inside of all paragraph blocks with Rick rolled!.
