设计模式--简单工厂

目标创建对象；

实现 1；实现工厂类 2；调用测试

 

<?php
//调用工厂类
require_once "./jiandangongcheng.php";
$po = array();
$po[] = pro::GetInstance(12,1);
$po[] = pro::GetInstance(1,11);
$po[] = pro::GetInstance(1,1);

foreach ($po as $key => $value) {
    if ($value) {
        echo "<br/>";
        $value->x_caozuo();
        echo "<br/>";
        $value->Y_caozuo();
    }else {
        echo "非法";
    }
    echo "<br/>";
}

 

　　

<?php
 //实现工厂类
interface product{
    function X_caozuo();
    function Y_caozuo();
}

class Xproduct implements product{
    
    function X_caozuo(){
        echo "我实现了X操作";
    }
    function Y_caozuo() {
        echo "我没有实现Y_操作 ";
    }

}

class Yproduct implements product {

    function x_caozuo() {
        echo "类Yproduct 没有实现X操作";
    }
    function Y_caozuo() {
        echo "类Yproduct 实现Y操作";
    }
}


class pro{
    static function GetInstance($x,$y){
        if ($x>1 && $y===1) {
            return new Xproduct();
        }elseif ($x == 1 && $y >1) {
            return new Yproduct();
        } else {
            return null;
        }
    }
}
