About this binding

class Human {
    public $name = &#39;lisi&#39;;    public function who() {
        echo $this->name;
    }    /*
    public function test() {
        echo $name;
    }
    *//*
和java、c++相比
方法体内想访问调用者的属性，必须用$this
如果不加，则理解为方法内部的一个局部变量.
*/}$a = new Human();echo $a->name,&#39;<br >&#39;; //lisi$a->who(); //lisi//$a->test();
