I have two questions related to OOP Inheritance object :
The first one is
that according to the below
code:class Test
{
private $name = "Youhana";
function getPrivate(){
echo $this->name ;
}
}
Class Test2 extends Test
{
}
$obj2 = new
Test2();
$obj2->getPrivate();
The
result will be => Youhana, but how does this work, despite the inheritance means that
members are cloned from the parent to child, so if this is correct, the code in the
child class must be like the below
logic:
Class Test2 {// simple
imagination to the Test2 after extends Test CLass
function
getPrivate(){ //which must return null not the value of the private member.
echo $this->name ;
}
}
Ref :
Manual
Second question is that consider the below
code:
Class
Ex1{
function checkClassName(){
var_dump(__CLASS__);
}
}
Class Ex2 extends
Ex1{
}
$obj2 = new
Ex2();
$obj2->checkClassName();//how this will return EX1
although we invoked this function from the second object which after the inheritance
will have a clone of public and protected members of the parent
class?
How
this will return EX1 although we invoked this function from the second object which
after the inheritance will have a clone of public and protected members of the parent
class?
