Ss是可能的, 在不使用C++中的“美元” 等“美元”的情况下, 访问本类方法中的类属性?

小型例子:

class MyClass
{
    protected $foo =  abc ;
    protected $bar =  dca ;

    public function __construct()
    {
        $foo =  Hello ;
        $bar =  World! ;
    }

    public function display()
    {
        echo $foo .     . $bar;
    }
}


$MyObject = new MyClass();
$MyObject->display();

In result, I have notices about undefined variables. But I ld like to be sure - is it possible, or not?

最佳回答

否。在 PHP 中,您必须使用 $nthis-gt; 语法来访问实例变量。
