25 种 php 设计模式, 你全都知道吗? 下面用代码介绍
命令模式 (command 模式)
- _command[] = $command;
- }
- public function executeCommand() {
- foreach ($this->_command as $command) {
- $command->execute();
- }
- }
- public function removeCommand($command) {
- $key = array_search($command, $this->_command);
- if ($key !== false) {
- unset($this->_command[$key]);
- }
- }
- }
- class Receiver {
- private $_name = null;
- public function __construct($name) {
- $this->_name = $name;
- }
- public function action() {
- echo $this->_name . "action";
- }
- public function action1() {
- echo $this->_name . "action1";
- }
- }
- class ConcreteCommand implements Command {
- private $_receiver;
- public function __construct($receiver) {
- $this->_receiver = $receiver;
- }
- public function execute() {
- $this->_receiver->action();
- }
- }
- class ConcreteCommand1 implements Command {
- private $_receiver;
- public function __construct($receiver) {
- $this->_receiver = $receiver;
- }
- public function execute() {
- $this->_receiver->action1();
- }
- }
- class ConcreteCommand2 implements Command {
- private $_receiver;
- public function __construct($receiver) {
- $this->_receiver = $receiver;
- }
- public function execute() {
- $this->_receiver->action();
- $this->_receiver->action1();
- }
- }
- $objRecevier = new Receiver("No.1");
- $objRecevier1 = new Receiver("No.2");
- $objRecevier2 = new Receiver("No.3");
- $objCommand = new ConcreteCommand($objRecevier);
- $objCommand1 = new ConcreteCommand1($objRecevier);
- $objCommand2 = new ConcreteCommand($objRecevier1);
- $objCommand3 = new ConcreteCommand1($objRecevier1);
- $objCommand4 = new ConcreteCommand2($objRecevier2); // 使用 Recevier 的两个方法
- $objInvoker = new Invoker();
- $objInvoker->setCommand($objCommand);
- $objInvoker->setCommand($objCommand1);
- $objInvoker->executeCommand();
- $objInvoker->removeCommand($objCommand1);
- $objInvoker->executeCommand();
- $objInvoker->setCommand($objCommand2);
- $objInvoker->setCommand($objCommand3);
- $objInvoker->setCommand($objCommand4);
- $objInvoker->executeCommand();
