Hello
Yes, you can change the protected attribute of the method in the extended class:
Code: Select all
class A {
protected function f1(){
return 'abc';
}
}
class B extends A {
public function f1(){
return 'xyz';
}
}
$ob = new B;
echo $ob->f1(); // xyz
In the same way, you can rewrite the protected method, maintaining the same attribute:
Code: Select all
class A {
protected function f1(){
return 'abc';
}
}
class B extends A {
protected function f1(){
return 'xyz';
}
public function f2(){
return 123 . $this->f1();
}
}
$ob = new B;
echo $ob->f2(); // 123xyz
