PHP - 在一个类中使用公共函数，但在扩展类中不使用

Question

I have 3 classes

class Header
{
    public function _after_save ()
    {
    }
}

class Line extends Header
{

}

class Details extends Line
{

}

Line extends header and Details extend line. Header has a function which 'll be called many pages in my site & I have made it public. I don't want when Line and Details class to call the function _after_save() to execute but it's getting executed as are extended classes. I can't make the function protected for obvious reasons. Any help how I can achieve this

Answer 1

You could create branched structure.

class AbstractHeader
{

}

class Header extends AbstractHeader
{
    public function _after_save ()
    {
    }
}

class Line extends AbstractHeader
{

}

class Details extends AbstractHeader
{

}
