// Start with some string
$input = 'Some string to parse';

// Create the instance of the Parser
$parser = new \Waynestate\ParserMiddleware\ParserMiddleware();

// Define the list of parsers to run, in chronological order
// Each must implement the Waynestate\StringParser\StringParserInterface
$parsers = array(
    'Waynestate\StringParser\SelfParser',
    'Waynestate\StringParsers\ReverseParser',
);

     * @param string $string
     * @return string
     */
    public function parse($string) {
