Hi, Coming from C++ world, i would like to know what in PHP, is the equivalent of namespace in C++ ? I have several class which should work together, or Class B which is used to create a private property of class A. How can i do that without including the class B into the class A definition ? thanks a lot, -- Alain ------------------------------------ Windows XP SP2 PostgreSQL 8.1.4 Apache 2.0.58 PHP 5
