本文主要是介绍类与接口的一个有趣程序例子,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
面向对象编程中,类和接口是最基础的两个概念了。下面写一个简单的程序,分别演示使用基类与接口如何编写程序。程序很简单,不用过多解释,直接上代码了。广大程序员兄弟们一定能够明白是什么意思吧。
先是类的方式。
<?php
/*** 类模式老婆* Wife基类*/
class Wife {public function Cook($howToCook, $vegetableArray) {$this->BuyVegetables ( $vegetableArray );for($i = 0; $i < count ( $howToCook ); $i ++) {//要吃的菜没有?买去if (in_array ( $howToCook [$i] ["one"], $vegetableArray )) {$this->BuyVegetables ( array ($howToCook [$i] ["one"] ) );} else if (in_array ( $howToCook [$i] ["two"], $vegetableArray )) {$this->BuyVegetables ( array ($howToCook [$i] ["two"] ) );} else {"做饭";}}}/*** 买菜* @param array $vegetableArray 菜名数组*/public function BuyVegetables($vegetableArray) {"去菜场买菜";}/*** 洗衣服*/public function WashClothes() {"1_干洗外套";"2_洗衣机洗裤子";"3_手洗袜子";}/*** 做家务*/public function DoHouseholdDuties() {"1_扫地";"2_拖地";"3_擦桌子";}
}/*** I类 继承Wife类* @author Samuel*/
class I extends Wife {/***打游戏 */function PlayGames() {"打游戏";}/*** 打篮球*/function PlayBasketball() {"打篮球";}/*** 看电视*/function WatchTV() {"看电视";}/*** 煮饭* @see Wife::Cook()*/function Cook() {//哥哥今天要吃的菜$howToCook = array (array ("one" => "猪肉", "two" => "芹菜", "operation" => "炒" ), array ("one" => "土豆", "two" => "牛肉", "operation" => "烧" ) );$vegetableArray = array ("猪肉", "鸡蛋", "酸奶", "香菇", "芹菜", "土豆", "牛肉" );parent::Cook ( $howToCook, $vegetableArray );}/*** 洗衣服* @see Wife::WashClothes()*/function WashClothes() {//调用Wife类洗衣服方法parent::WashClothes ();}/*** 做家务* @see Wife::DoHouseholdDuties()*/function DoHouseholdDuties() {//调用Wife类做家务方法parent::DoHouseholdDuties ();}
}
?>
然后是接口的方式:然后是接口的方式:
<?php
/*** 接口模式老婆* Wife接口*/
interface Wife {/*** 煮饭* @param array $howToCook 菜的做法* @param array $vegetableArray 需买的菜的数组*/function Cook($howToCook, $vegetableArray) {}/*** 买菜* @param array $vegetableArray 菜名数组*/function BuyVegetables($vegetableArray) {}/*** 洗衣服*/function WashClothes() {}/*** 做家务*/function DoHouseholdDuties() {}
}/*** I类 实现Wife接口* @author Samuel*/
class I implements Wife {/***打游戏 */function PlayGames() {"打游戏";}/*** 打篮球*/function PlayBasketball() {"打篮球";}/*** 看电视*/function WatchTV() {"看电视";}/*** 煮饭* @param array $howToCook 菜的做法* @param array $vegetableArray 需买的菜的数组*/public function Cook($howToCook, $vegetableArray) {$this->BuyVegetables ( $vegetableArray );for($i = 0; $i < count ( $howToCook ); $i ++) {//要吃的菜没有?买去if (in_array ( $howToCook [$i] ["one"], $vegetableArray )) {$this->BuyVegetables ( array ($howToCook [$i] ["one"] ) );} else if (in_array ( $howToCook [$i] ["two"], $vegetableArray )) {$this->BuyVegetables ( array ($howToCook [$i] ["two"] ) );} else {"做饭";}}}/*** 买菜* @param array $vegetableArray 菜名数组*/public function BuyVegetables($vegetableArray) {"去菜场买菜";}/*** 洗衣服*/public function WashClothes() {"1_干洗外套";"2_洗衣机洗裤子";"3_手洗袜子";}/*** 做家务*/public function DoHouseholdDuties() {"1_扫地";"2_拖地";"3_擦桌子";}
}
?>
