用PHP包？

[英]Packages in PHP?

原文 2009-02-10 22:29:21 7 4 php/ oop/ php-packages

Is it possible to create packages of related classes and have the same protected and private fields which are visible only to classes from within the same package? 是否可以创建相关类的包并具有相同的protected和private字段，这些字段仅对同一个包中的类可见？

Basically, the same type of packages as what Java has. 基本上，与Java具有相同类型的包。 Is it possible? 可能吗？

However, PHP 5.3 is going to introduce namespaces . 但是，PHP 5.3将引入名称空间。 I'm not sure about how that will affect visibility between classes. 我不确定这将如何影响课程之间的可见性。

Nope. 不。 PHP has no package or friend-class support. PHP没有包或朋友级支持。
