Three ways to use PHP namespace

PHP 5.3 In namespace is actually a good thing, you can simplify the programming, the following describes the three categories in the code
Methods for accessing classes in namespace
1 referencing namespace and classes
Suppose the namespace program is namespaced-class.php

namespace Christmas\daysof;  Class partridgeinapeartree{}

Reference method:

  Include ' namespaced-class.php '; $bird 1 = new Christmas\daysof\partridgeinapeartree (); Var_dump ($bird 1);

At this time, new has introduced the complete namespace and the following classes.
2 Partial references

  Include ' namespaced-class.php '; use christmas\daysof; $bird 2 = new Daysof\partridgeinapeartree (); Var_dump ($bird 2);

With the use specified in the namespace, it is only necessary to refer to the last part of the namespace when using Daysof.
3 The simplest

Include ' namespaced-class.php '; use Christmas\daysof\partridgeinapeartree as Bird;            $bird 3 = new Bird (); Var_dump ($bird 3);

In this case, the specified class under the namespace is replaced by a custom name, which is very convenient.
