Hi all, If you are designing with OO principles, could you give an explanation of what is the difference classes and packages? Several principles talks about classes and packages, such as: The classes in a package are reused together. If you reuse one of the classes in a package, you reuse them all. but few explains the difference between them. When I was summarizing the OO principles, that question confused me: http://phparch.cn/index.php/php/43-php-advanced-programming/170-principles-of-object-oriented-design Thanks in advance. :) -- Regards, Shelley
