Answer 1

As i said, problem is not in permissions i resolve problem with dirname(__FILE__)

code:

    if (!is_dir(dirname(__FILE__) . '/../media/catalog/product/' . $firstFolderName)) {
                mkdir(dirname(__FILE__) . '/../media/catalog/product/' . $firstFolderName, 0777, true);
            } else {
                mkdir(dirname(__FILE__) . '/../media/catalog/product/' . $firstFolderName . '/' . $secondFolderName, 0777, true);
            }

....

move_uploaded_file($file_tmp, dirname(__FILE__) . '/../media/catalog/product/' . $firstFolderName . '/' . $secondFolderName . '/' . $file_name);
