我有PHP代码
<?
class AParent {
function to_s() {
return $this->id;
}
}
class AChild {
public $id;
public $name;
function to_s() {
if(!empty($this->name)) {
$ret = $this->name;
} else {
$ret = /** call parent's method to_s() */
}
return $ret;
}
}
如何调用在孩子中超载的父母方法? :)有可能使用静态方法,但如何使用非静态方法?
$a = new AChild();
$a->id = 1;
$a->name = 'Something';
echo $a; // Should echo "Something"
$b = new AChild();
$b->id = 2;
echo $b; // Should echo "2"
答案 0 :(得分:0)
使用$ret = parent::to_s()
,就够了
