Class Basics

Class structures use namespacing too, just like functions do. Within its namespace, PHP knows how to find the methods and properties of a class blueprint. When you use the class outside of the namespace, you need to make PHP know which class you mean. That means you can either:

• You can specify its fully qualified name such as \KnowTheCode\InsOutsPHPNamespacing\Sandbox\Post
• If the namespace is the root, then you can use a relative name such as $post = new Sandbox\Post();
• You can import the class using the PHP keyword use.
• You can import and then alias the class.

You can learn more about aliasing and importing in the PHP manual.
