abstract class ClassParent {
    public static $var1 = "ClassParent";
}

class ClassChild1 extends ClassParent{
    public static function setvar1(){
        ClassChild1::$var1 = "ClassChild1";     
    }
}

class ClassChild2 extends ClassParent{
    public static function setvar1(){
        ClassChild2::$var1 = "ClassChild2";
    }
}


ClassChild1::setvar1();

echo ClassChild2::$var1;
// Returns "ClassChild1". Shouldn't this still be "ClassParent"?

我假设上述是预期的行为,而不是PHP错误.在这种情况下,我怎么能在父类中声明一个静态变量,这个变量将被单独处理为子类.换句话说,我想要具有单独的静态值PER CHILD CLASS.我必须在小孩类中特别声明静态变量,还有另一种方式吗？@H_502_4@
