<?php
    public function main($sourceFileName)
    {
        $results[] = $sourceFileName;

$results was never initialized. Although not strictly required by PHP, it is generally a good practice to add $results = array(); before regardless.

        $mapper = null;

The assignment to $mapper is dead and can be removed.

        foreach ($this->getMappers() as $mapper) {
            if (null !== $mapper) {
                $inputs = $results;
                $results = [];

                foreach ($inputs as $input) {
                    $mapped = $mapper->getImplementation()->main($input);
                    if (null != $mapped) {
                        $results = $mapped;
                    }
                }
            }
        }

        return !empty($results) ? $results : null;
    }
