Да мне тоже не нравится все эти серверные прибамбасы.
И вообще структура вроде такой.

Но, всё таки писать классы на стороне сервера для задач, это штука классная. Я попробовал на днях, мне понравилось.
Поэтому ищу уже реализованные классы.
Например FPDF вроде хороший.
У zend тоже есть класс для работы с pdf.
