PHP设计模式之外观模式（Facade）入门与应用详解

<?php
//外观模式，通过在必须的逻辑和方法的集合前创建简单的外观接口，外观设计模式隐藏了来自调用对象的复杂性
class User {
 protected $userName;
 protected $userAge;
 public function setUserName($userName) {
 return $this->userName = $userName;
 }
 public function setUserAge($userAge) {
 return $this->userAge = $userAge;
 }
 public function getUser() {
 echo '用户姓名：' . $this->userName . '； 用户年龄：' . $this->userAge;
 }
}
//创建一个User 类调用接口，简化获取用户getUser方法的调用
class UserFacade {
 public static function getUserCall($userInfo) {
 $User = new User;
 $User->setUserName($userInfo['username']);
 $User->setUserAge($userInfo['userAge']);
 return $User->getUser();
 }
}
$userInfo = array('username' => 'initphp', 'userAge' => 12);
UserFacade::getUserCall($userInfo); //只要一个函数就能将调用类简化
