php调用函数->和::有什么区别吗???
php调用函数->和::有什么区别吗???

------解决方案--------------------
...你回头看哈书吧,类的那个章节,
::是调用父类(parent)、自己(self)或者直接调用类的静态函数(class::method())等
->是实例化后的调用($class->method()),当然要注意this这个特殊的调用自身等情况($this->method(), $this->variable)
------解决方案--------------------
静态调用和动态调用的的区别
------解决方案--------------------
->调用实例方法
::调用静态方法
