析构函数

1.__destruct

当对象销毁时候，自动调用方法

<?php
class show{
function __construct(){
}
}
?>

<?php

class show{
    private $name;
    private $big;
    public function __construct($name){
    $this->name=$name;
    echo "{$name} 诞生了<br>";
    }
    public function __destruct(){
        echo "{$this->name} 销毁了<br>";
    }
}

$stu=new show('test');
?>
