php 工厂模式

1. 基本工厂
   

   class User {   
       private $username;   
       public function __construct($username) {   
           $this->username = $username;   
       }   
         
       public function getUser() {   
           return $this->username;   
       }   
   }  
     
   class userFactory {   
       static public function createUser() {   
           return new User('Jack');   
       }   
   }  
     
   $user = userFactory::createUser();echo $user->getUser();

2. 简单工厂模式

   interface userProperties {  
       function getUsername();  
       function getGender();  
       function getJob();  
   }  
   class User implements userProperties{  
       private $username;  
       private $gender;  
       private $job;  
       public function __construct($username, $gender, $job) {  
           $this->username = $username;  
           $this->gender = $gender;  
           $this->job = $job;  
       }  
     
       public function getUsername() {  
           return $this->username;  
       }  
     
       public function getGender() {  
           return $this->gender;  
       }  
     
       public function getJob() {  
           return $this->job;  
       }  
   }  
     
   class userFactory {  
       static public function createUser($properties = []) {  
           return new User($properties['username'], $properties['gender'], $properties['job']);  
       }  
   }  
     
   $employers = [  
       ['username' => 'Jack', 'gender' => 'male', 'job' => 'coder'],  
       ['username' => 'Marry', 'gender' => 'female', 'job' => 'designer'],  
       ];  
   $user = userFactory::createUser($employers[0]);  
   echo $user->getUsername();  

3. 抽象工厂模式

   interface userProperties {  
       function getUsername();  
       function getGender();  
       function getJob();  
   }  
     
   interface createUser { //将对象的创建抽象成一个接口  
       function createOpen($properties);//内向创建  
       function createIntro($properties);//外向创建  
   }  
     
   class User implements userProperties{  
       private $username;  
       private $gender;  
       private $job;  
       public function __construct($username, $gender, $job) {  
           $this->username = $username;  
           $this->gender = $gender;  
           $this->job = $job;  
       }  
     
       public function getUsername() {  
           return $this->username;  
       }  
     
       public function getGender() {  
           return $this->gender;  
       }  
     
       public function getJob() {  
           return $this->job;  
       }  
   }  
     
   class userFactory {  
       private $user;  
       public function __construct($properties = []) {  
           $this->user =  new User($properties['username'], $properties['gender'], $properties['job']);  
       }  
     
       public function getUser() {  
           return $this->user;  
       }  
   }  
     
   class FactoryMan implements createUser {  
       function createOpen($properties) {  
           return new userFactory($properties);   
       }  
     
       function createIntro($properties) {  
           return new userFactory($properties);   
       }  
   }   
     
   class FactoryWoman implements createUser {  
       function createOpen($properties) {  
           return new userFactory($properties);  
       }  
     
       function createIntro($properties) {  
           return new userFactory($properties);  
       }  
   }  
     
   class clientUser {  
       static public function getClient($properties) {  
           $fac = new FactoryMan;  
           $man = $fac->createOpen($properties);  
           return $man->getUser()->getUsername();  
       }  
   }  
     
   $employers = [  
       ['username' => 'Jack', 'gender' => 'male', 'job' => 'coder'],  
       ['username' => 'Marry', 'gender' => 'female', 'job' => 'designer'],  
       ];  
   $user  = clientUser::getClient($employers[0]);
   $user1 = clientUser::getClient($employers[1]);
   $user2 = clientUser::getClient($employers[0]);
   $user3 = clientUser::getClient($employers[1]);
   var_dump($user,$user1,$user2,$user3);
