MaglMarkdown is a ZF2 module that adds a View Helper to transform Markdown. To change between different renderers have a look at the config section

You can use one of the following parsers for your Markdown:


You can install the module with composer by adding the following "require" to your composer.json

    "require": {
        "maglnet/magl-markdown": "~1.1"

after that you need to run

$ php composer.phar update

and enable the module within your application.config.php

    'modules' => array(


View Helper

Simply use it within your Views like this

$this->markdown('Yes, **this** is *Markdown*!');

Service Manager

You can get the MarkdownService through the Service Manager, to use the render() method wherever you like within you zf2 application. MarkdownService automatically uses caching if it has been enabled within the config.

/* @var $markdownService MaglMarkdown\Service\Markdown */
$markdownService = $serviceManager->get('MaglMarkdown\MarkdownService');
$html = $markdownService->render('Yes, **this** is *Markdown*!');

You can also get a MarkdownAdapter through the Service Manager and use transformText() to get your Markdown rendered to HTML.
This is NOT recommended anymore. Use the above mentioned MarkdownService instead because it can use the provided caching mechanism.

/* @var $markdownAdapter MaglMarkdown\Adapter\MarkdownAdapterInterface */
$markdownAdapter = $serviceManager->get('MaglMarkdown\MarkdownAdapter');
$html = $markdownAdapter->transformText('Yes, **this** is *Markdown*!');

Security warning:
You should be aware, that your markdown could contain insecure content (e.g. user generated content). So use something like HTMLPurifier to sanitize your output.


Copy the provided config file config/maglmarkdown.local.php to your autoloading directory YourZF2Application/config/autoload/maglmarkdown.local.php and adjust it to your needs.
By default PHP-MarkdownExtra parser by Michel Fortin is used.


By default, caching is disabled. Set cache_enabled to true within config/maglmarkdown.local.php to enable the caching. Caching could be very helpful if you have large markdown files/texts or if you're using an Adapter that relies on third-party APIs that either are rate limited or take a long time to render.

A simple filesystem cache is configured by default, but feel free to configure your own adapter.

Adding own parsers

It is possible to add your own parser implementation.
All you have to do, is to write a class that implements the MaglMarkdown\Adapter\MarkdownAdapterInterface interface and make it available through the service manager.
After that override the alias MaglMarkdown\MarkdownAdapterto point to your custom adapter.
MaglMarkdown will then use this class to transform the Markdown.

    'aliases' => array(
        'MaglMarkdown\MarkdownAdapter' => 'Your\Own\MarkdownAdapter', //needs to implement MaglMarkdown\Adapter\MarkdownAdapterInterface


The markdown service triggers two events you can listen to:

  • markdown.render.pre before rendering (with the markdown text as parameter)
  • after rendering (with the rendered markdown as parameter)

These events are currently used for the integrated caching feature only, but do whatever you like with these events.
