код формы

• Автоматическое форматирование кода Linux (PHP, JavaScript, HTML, CSS, MySQL)
• Как декодировать такую ​​странную строку в UTF-8? (PHP)
• Сообщение об ошибке проверки правильной формы для Codeigniter 2
• как придерживаться принципа Don't-Repeat-Yourself (DRY), когда будет слишком много if-then-else, делая код нечитаемым?
• CodeIgniter - Требуется подтверждение загрузки файла
