本篇文章是对php中的self与$this进行了详细的分析介绍,需要的朋友参考下

先谈parent与self:

复制代码 代码如下:


/*
* Created by YinYiNiao
*/
class A{
function __construct(){
echo "基类A的构造方法
";
}
}
class B extends A{
function __construct(){
parent::__construct();
echo "子类B的构造方法
";
self::myFun();
}
function myfun(){
echo "一个普通方法myFun()
";
}
}
$obj=new A();
$obj=new B();
?>


self与$this的功能极其相似,香港虚拟主机,但二者又不相同。$this不能引用静态成员和常量。self更像类本事,而$this更像是实例本身。
