PHP面向对象构造和析构函数

	<?php
	class Ren{
		public $name;
		public $sex;//性别是人一出生就知道的，可以用构造函数来定义
		/*public function Ren(){
		} */
		//构造函数不常用
		public function __construct(){	
		}//构造函数常用
	}
    ?>

	<?php
	class Ren{
		public $name;
		public $sex;
		public function __construct($sex){
			$this->sex = $sex;
			echo "测试一下";
		}
	}
	$r = new Ren("男");
	$r->name = "张三";
	var_dump($r);
    ?>

	<?php
	class Ren{
		public $name;
		public $sex;
		public function __construct($sex){
			$this->sex = $sex;
		}
		public function __destruct(){
			echo "销毁";
		}//执行完name后没有可执行的 会自动销毁内容
	}
	$r = new Ren("男");
	$r->name = "张三";
    ?>
