[Excuse me] CakePHPnamespace/interface/inherit

[Consultation] Hello, CakePHPnamespace/interface/inherit. I have the following questions: I was a. NET Developer (I have some J2EE experience ). The next project uses PHP and the framework uses CakePHP. PHP has the namespace/interface/inherit syntax similar to. NET, or [ask] CakePHP namespace/interface/inherit
Hello, I have the following questions. please advise:

I was a. NET Developer (I have some J2EE experience ).

The next project uses PHP and the framework uses CakePHP.
PHP itself has namespace/interface/inherit, which is similar to. NET syntax or architecture structure,
However, in CakePHP, I searched these DongDong online for a long time and read a lot of teaching materials. I didn't find any?
In OOP, whether it is. NET or J2EE, these are basic content. if there is no such content in CakePHP, it is inconvenient to design the architecture ....

Thank you!

------ Solution --------------------
Php I have never used a namespace. it seems that the namespace is newly added in 5.3.
PHP is often used in oop.
------ Solution --------------------
Cakephp does have few materials. you need to check the official documents ./

What you said about PHP was previously unavailable. it was added later, but it didn't make much sense. Each language has its own design style and writing specifications. Some of other languages do not necessarily exist in other languages. Although the goals are the same, the implementation methods have their own characteristics, advantages and disadvantages.
