请问 【public function __call($name,$args)】中$name ,$args 在属性上有什么区别?
<?php
/*class Car {
public $speed = 10;
//在这里使用重载实现speedDown方法
}
$car = new Car();
$car->speedDown(); //调用不存在的speedDown方法
echo $car->speed;*/
class Car {
public $speed = 0;
public function __call($name,$args) {
if ($name == 'speedUp'){
$this->speed += 10;
}
}
}
$car = new Car();
$car->speedUp();
echo $car->speed;
