Pandoc PHP is a naive wrapper for the Pandoc command. Pandoc is a Haskell program that allows you to convert documents from one format to another. For more information on Pandoc you can look here.

First you will need Pandoc. The easiest method to get this is with a quick cabal install pandoc providing you have Haskell installed. (apt-get also supports installation of Pandoc using apt-get install pandoc you just need to make sure you have at least version 1.10 for this library).

The recommended method to installing Pandoc PHP is with composer

{
    "require": {
        "ryakad/pandoc-php": "~1.0"
    }
}

Once installed you can start converting your content to other formats like:

$pandoc = new Pandoc();
$html = $pandoc->convert("#Hello Pandoc", "markdown_github", "html");
// $html == "<h1>Hello Pandoc</h1>"

For a full listing of formats that can be converted to/from you should take a look at the Pandoc documentation or the Pandoc help message pandoc --help.

If you need more control over how the conversion will be executed, use the runWith method. This method takes two arguments, content to convert and an array containing options. The options array can hold any of the pandoc command line options, see pandoc --help.

$pandoc = new Pandoc\Pandoc();
$options = array(
    "from"  => "markdown",
    "to"    => "html",
    "css"   => "/assets/css/documents.css"
);
$html = $pandoc->runWith("#Hello Pandoc", $options);
