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();其他相关设计模式：
