是否可以扩展类而不扩展此类的方法？

Question

The title says it all. I have a class with a lot of variables and a lot of methods in it.

class bootstrap_class { 
public
//-----Counters--------- 
$iColumn_count,
$iLink_count,
$iDia_count,
$iTab_count,
$iPadding,
$iColumns_per_page,

//-----Strings---------
$sCentered, 
$sClass,
etc;

public function a () {
    //do something
}

public function b () {
    //do something
}
}

I am trying to extend this class to create a class without all the methods. I then want to store this new class object into an array variable in the parent class.

Is it possible to extend a class without extending the functions of that class?

Answer 1

It is not possible the way you want it. But The following is the only way to do it.

All you have to do is change the methods' visibility to private from public in parent class. See below for details.
