"Excuse Me" CakePHP namespace/interface/inherit

"Ask" CakePHP Namespace/interface/inherit
Hello, I have the following questions, please advise:

I was originally. NET-Department developer (and some experience with EE).

The next project uses PHP, the framework used by cakephp.
PHP itself has namespace/interface/inherit these with. NET-like syntax or an architecture structure,
But cakephp, these several things online search for half a day, textbooks also looked at a lot, also did not find AH?
In OOP, no matter what. NET or Java EE, these are the basic content, if there is no word in cakephp, the architecture design can be inconvenient ....

Thank you!

------Solution--------------------
PHP I didn't use the namespace seems to be 5.3 new add in
PHP is very common with OOP.

There is really little data on cakephp and you need to check the official documentation.

You said these things PHP was not originally, and later added, but the meaning is not big. Each language has its own design style and writing specifications. In other languages there is not necessarily another language. Although the goal is the same, the method of implementation has its own characteristics, advantages and disadvantages.
