类文件:
实例
<?php /** * */ class GirlFriend1 { //类成员:属性、方法 //类属性:初始化必须使用标量的字面量、数组 private $name = ''; private $age = 0; private $stature = []; //声明构造方法:实例化是自动调用 //功能:对象初始化 public function __construct($name, $age,array $stature) { $this->name = $name; $this->age = $age; $this->stature = $stature; } public function getName() { return $this->name; } public function getAge() { return $this->age; } public function getStature() { return print_r($this->stature,true); } //获取器 public function __get($name) { return $this->$name; } //设置器 public function __set($name,$value) { $this->$name = $value; } }
