php set and get function

[chaiwei]

Hi,

 

I was concern about the php class.

If I got a class which have 100 private variables,

So normally with php magic function, I can

 

public function __set($name , $value){ xxx }

public function __get($name ){ xxx }

 

So I don't have to have 100 set function and 100 get function.

 

But with those magic function I wouldn't have to declare the variable inside the class,

So I doesn't have the references for me to refer, so I tend to forget the variable naming.

Like I name my employee id variable -> $empId

May be my friend name the variable -> $employee_id

 

So this is not the same.

If we are using the same class to develop a employee system,

May be my function can't pass the value to his function.

How to overcome this issues with those magic function?

You can use the magic __isset method to validate whether an attribute exists or not, calling it within your magic getters/setters.

 

PS 100 attributes is a lot, do you really need that many?

I see..

 

No.. it was just an example..

Let say an employee class,

Should I seperate out the personal information class and job class (contract / permanent)?

OR combine it inside an employee class?

 

So if seperate I should use inheritance right?

Another thing was If I am using those magic method,

what is the difference for me to set those variable to public?

 

Thanks for the advices.

Normally I should seperate the job object and employee object to two different object right?
