Methods for accessing classes in namespace

1 Reference namespace and class
Assume that the namespace program is a namespaced-class.php
Namespace Christmas \ DaysOf;

Class PartridgeInAPearTree {
}


Reference method:
Include 'namespaced-class. php ';

$ Bird1 = new Christmas \ DaysOf \ PartridgeInAPearTree ();
Var_dump ($ bird1 );

At this time, the complete namespace and the following classes are introduced in NEW.

2 Part references
Include 'namespaced-class. php ';
Use Christmas \ DaysOf;

$ Bird2 = new DaysOf \ PartridgeInAPearTree ();
Var_dump ($ bird2 );
After the namespace is specified in USE, you only need to reference the last part of the namespace Daysof.

3. simplest
Include 'namespaced-class. php ';
Use Christmas \ DaysOf \ PartridgeInAPearTree as Bird;

$ Bird3 = new Bird ();
Var_dump ($ bird3 );

The specified class in the namespace is replaced by a custom name, which is very convenient.
