关于继承的一点疑惑，希望大家可以帮帮忙！
class f {
private $str = "123";
public function fun() {
echo $this->str;
}
}
class s extends f {
public $str = "abc";
}
$s = new s();
$s->fun();
输出：123
class f {
public $str = "123";
public function fun() {
echo $this->str;
}
}
class s extends f {
public $str = "abc";
}
$s = new s();
$s->fun();
输出：abc
第一个的输出很疑惑，为什么会输出父类的属性值？麻烦大家给我分析分析内存，有图说明更好，谢谢大家了。
