假设一个具有定义的__get()的抽象基类foo,以及一个从foo继承私有变量$var的子类bar,当尝试从类之外访问私有的$var时,调用父__get() ？
是.
<?PHP
abstract class foo
{
public function __get($var)
{
echo "Parent (Foo) __get() called for $var\n";
}
}
class bar extends foo
{
private $var;
public function __construct()
{
$this->var = "25\n";
}
public function getvar()
{
return $this->var;
}
}
$obj = new bar();
echo $obj->var;
echo $obj->getvar();
?>
输出：
$PHP test.PHP
父(Foo)__get()调用var
25
