Usage

Then include Composer’s generated vendor/autoload.php to enable autoloading:

require 'vendor/autoload.php';

Without Composer, for autoloading to work, your project needs an autoloader compatible with PSR-4 or PSR-0. See the included Readme.php file for a minimal autoloader setup. (If you cannot use autoloading, see below.)

With class autoloading in place:

use Michelf\Markdown;
$my_html = Markdown::defaultTransform($my_text);

Markdown Extra syntax is also available the same way:

use Michelf\MarkdownExtra;
$my_html = MarkdownExtra::defaultTransform($my_text);

If you wish to use PHP Markdown with another text filter function built to parse HTML, you should filter the text after the transform function call. This is an example with PHP SmartyPants:

use Michelf\Markdown, Michelf\SmartyPants;
$my_html = Markdown::defaultTransform($my_text);
$my_html = SmartyPants::defaultTransform($my_html);

All these examples are using the static defaultTransform static function found inside the parser class. If you want to customize the parser configuration, you can also instantiate it directly and change some configuration variables:

use Michelf\MarkdownExtra;
$parser = new MarkdownExtra;
$parser->fn_id_prefix = "post22-";
$my_html = $parser->transform($my_text);

To learn more, see the full list of configuration variables.
