I'm having a hard time trying to understand the output of the following code:
class Bar
{
public function test() {
$this->testPublic();
$this->testPrivate();
}
public function testPublic() {
echo "Bar::testPublic
";
}
private function testPrivate() {
echo "Bar::testPrivate
";
}
}
class Foo extends Bar
{
public function testPublic() {
echo "Foo::testPublic
";
}
private function testPrivate() {
echo "Foo::testPrivate
";
}
}
$myFoo = new foo();
$myFoo->test();
Output:
Foo::testPublic
Bar::testPrivate
Class Foo overrides testPublic() and testPrivate(), and inherits test(). When I call test(), there is an explicit instruction envolving $this pseudo variable, so after I created $myFoo instance, the final calls of test() function would be $myFoo->testPublic() and $myFoo->testPrivate(). The first output is as I expected, since I overrode testPublic() method to echo Foo::testPublic. But the second output makes no sense to me. Why is it Bar::testPrivate if I overrode testPrivate() method? Also the private method from parent class wouldn't be inherited anyway, by definition! It makes no sense. Why is the parent method the one being called???
