Summary: How to call an overridden non static method in the parent class ?
Calling an overridden static method is easy, just go: parent::MethodName().
The point is that I want to have the same 'output' method name in both classes,
so that whatever has one of them just calls $xxx->output() and it will work.
I want the method in the child class to use what the parent class has and just
add a bit to it. I don't want to duplicate a lot of code in class B that is
already in class A.
The way that I have a (hopefully temporary) workaround is to in class A have a
method do_output() that is called by A::output() and B::output(). That works,
but is clunky.
Is there a neat way of doing what I want ?
class A {
private $v_a;
// Does all sorts of things and returns a value
function output() {
return array('a' => $this->v_a);
}
}
class B extends A {
private $v_b;
// Takes what output() in class A returns, adds some more and returns that
function output() {
$ret = parent::output();
$ret['b'] = $this->v_b;
return $ret;
}
}
$var_a = new A;
$var_b = new B;
print_r($var_a->output());
// I want to see the value of v_a and v_b:
print_r($var_b->output());
