PHP设计模式-简单工厂模式
核心：
一、定义一个接口类里面写规定好的方法。
interface Message{public function send(array $params);public function getMessage(array $params);public function getCode(array $params);}
二、定义产品类 、产品类继承接口类
class AlliYunSms implements Message{public function send(array $params){return '发送短信';}public function getMessage(array $params){return '短信内容';}public function getCode(array $params){return '短信验证码';}}class QQSms implements Message{public function send(array $params){return '发送短信';}public function getMessage(array $params){return '短信内容';}public function getCode(array $params){return '短信验证码';}}class BaiduSms implements Message{public function send(array $params){return '发送短信';}public function getMessage(array $params){return '短信内容';}public function getCode(array $params){return '短信验证码';}}
三、编写工厂类实现业务
class SmsFactory{public $service=['aliyun' => AlliYunSms::class,'qq' => QQSms::class,'baidu' => BaiduSms::class];public $MsgService;public function __construct($type){if(!isset($this->service[$type])){throw new \Exception('短信服务不存在');}$this->MsgService = $this->service[$type];}public static function create(string $type){$class = __NAMESPACE__.'\\'.$type.'Sms';return new $class();}public function send(array $params){$this->MsgService->send($params);//业务逻辑return '发送成功';}}$service=new SmsFactory('aliyun');$service->send(['name'=>'thinkphp'])

大家有更好的写法请欢迎讨论
