Subject: [PATCH] Fix show command for PHP >= 7.0.0

- Implemented the methods showIni and showSection;
- The showIni can display data if it's empty, an array or only a value;
- It's important to note that this code rely on the process_sections
  argument from the parse_ini_file function and this processing is
  somehow weak, because it depends on the existence of the '[SECTION_NAME]'
  and the 'section_name.' is not interpreted as a section;
