本篇章节讲授PHP计划模式之原型计划模式道理与用法。分享给各人供各人参考，详细如下： 一、什么是原型计划模式原型计划模式行使一种克隆技能来复制实例化的工具，新工具是通过复制原型实例建设的。原型计划模式的目标是通过行使克隆以镌汰 实例化工具的开销。 在原型计划模式中，Client类是不行缺傲幽一部门。 PHP有一个内置的克隆要领 二、什么时辰行使原型计划模式假如一个项目要求你建设某个原型工具的多个实例，就可以行使原型计划模式。 三、原型计划模式实例这里以当代企业组织为例： dept; } //员工ID号配置要领 public function setId($id) { $this->id = $id; } //员工ID号获取要领 public function getId() { return $this->id; } //员工名字配置要领 public function setName($name) { $this->name = $name; } //员工名字获取要领 public function getName() { return $this->name; } } //市场部类 class Marketing extends IAcmePrototype { const UNIT = "Marketing"; //标识 //市场部分种别 private $sales = "sales"; private $promotion = "promotion"; private $strategic = "strategic planning"; //克隆函数 function __clone() { } //部分配置函数 public function setDept($orgCode) { switch($orgCode) { case 101: $this->dept = $this->sales; break; case 102: $this->dept = $this->promotion; break; case 103: $this->dept = $this->strategic; break; default: $this->dept = "Unrecognized Marketing"; } } } //打点部类 class Management extends IAcmePrototype { const UNIT = "Management"; private $research = "research"; private $plan = "planning"; private $operations = "operations"; function __clone() { } public function setDept($orgCode) { switch($orgCode) { case 201: $this->dept = $this->research; break; case 202: $this->dept = $this->plan; break; case 203: $this->dept = $this->operations; break; default: $this->dept = "Unrecognized Marketing"; } } } //工场部类 class Engineering extends IAcmePrototype { const UNIT = "Engineering"; private $development = "programming"; private $design = "digital artwork"; private $sysAd = "system administration"; function __clone() { } public function setDept($orgCode) { switch($orgCode) { case 301: $this->dept = $this->development; break; case 302: $this->dept = $this->design; break; case 303: $this->dept = $this->sysAd; break; default: $this->dept = "Unrecognized Marketing"; } } } //客户类 class Client { private $market; //市场部类实例 private $manage; //打点部类实例 private $engineer; //工场部类实例 //结构函数 public function __construct() { $this->makeConProto(); //市场部类实例克隆 $Tess = clone $this->market; $this->setEmployee($Tess,"Tess Smith",101,"ts101-1234"); $this->showEmployee($Tess); $Jacob = clone $this->market; $this->setEmployee($Jacob,"Jacob Jones",102,"jj101-2234"); $this->showEmployee($Jacob); //打点部类实例克隆 $Ricky = clone $this->manage; $this->setEmployee($Ricky,"Ricky Rodrigues",203,"rr203-5634"); $this->showEmployee($Ricky); //工程部类实例克隆 $Olivia = clone $this->engineer; $this->setEmployee($Olivia,"Olivia perez",302,"op302-1278"); $this->showEmployee($Olivia); $John = clone $this->engineer; $this->setEmployee($John,"John Jackson",301,"jj301-1454"); $this->showEmployee($John); } //实例化部分工具 private function makeConProto() { $this->market = new Marketing(); $this->manage = new Management(); $this->engineer = new Engineering(); } //员工信息配置要领 private function setEmployee(IAcmePrototype $employee,$name,$dept,$id) { $employee->setName($name); $employee->setDept($dept); $employee->setId($id); } //员工信息表现要领 private function showEmployee(IAcmePrototype $employee) { echo $employee->getName() . ''; echo $employee->getDept() . ' '; echo $employee->getId() . ' '; } } $client = new Client(); ?> 运行功效：
