php与设计模式-建造者模式

建造者模式

将一个复杂对象的构建与它的表示分离,使用同样的构建过程可以创建不同的表示
Demo

//用户类
class UserInfo
{
    protected $_userName;
    protected $_userAge;
    protected $_userHobby;

    public function setUserName($userName)
    {
        $this->_userName = $userName;
    }

    public function setUserAge($userAge)
    {
        $this->_userAge = $userAge;
    }

    public function setUserHobby($userHobby)
    {
        $this->_userHobby = $userHobby;
    }

    public function getPeopleInfo()
    {
        echo  "<br>这个人的名字是：" . $this->_userName . "<br>年龄为：" . $this->_userAge . "<br>  爱好：" . $this->_userHobby;
    }
}

这时候我们要获取一个用户的信息，过程是这样的：
$modelUser = new UserInfo();
$modelUser->setUserName('松涛');
$modelUser->setUserAge('23');
$modelUser->setUserHobby('推理小说');
$modelUser->getPeopleInfo();

这时候创建一个用户建造者类
class UserBuilder
{
    protected $_obj;

    public function __construct()
    {
        $this->_obj = new UserInfo();
    }

    public function builderPeople($userInfo)
    {
        $this->_obj->setUserName($userInfo['userName']);
        $this->_obj->setUserAge($userInfo['userAge']);
        $this->_obj->setUserHobby($userInfo['userHobby']);
    }

    public function getBuliderPeopleInfo()
    {
        $this->_obj->getPeopleInfo();
    }
}
这个是将复杂的创建过程封装在了builderPeople这个方法里面。 接下来是创建对象:
$userArr = array(
    'userName' => '松涛',
    'userAge' => '23',
    'userHobby' => '推理小说');

$modelUserBuilder = new UserBuilder();
$modelUserBuilder->builderPeople($userArr);
$modelUserBuilder->getBuliderPeopleInfo();
