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。
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:
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"; } } ?>
