php面向对象之类的创建

<?php
class Car
{
    public function __construct($name)#构造函数
    {
        $this->name = $name;
    }
    public function __destruct()#析构函数
    {
        echo "删除对象";
    }

    private $name;

    public function set_name($name)
    {
        $this->name = $name;
    }
    public function print_name()
    {
        printf("%s\n", $this->name);
    }
};
    $name = "hongqi";
    $car = new Car($name); #使用new定义对象
    $car->print_name();

    $name = "benchi";
    $car->set_name($name);
    $car->print_name();
?>
