php 橋接模式

交接模式之類比毛筆

(1) 實作類別介面

interface Color{public function bepaint($penType,$name);}

(2) 具體實現顏色類

class Red implements Color{public function bepaint($penType, $name) {echo $penType.'紅色的'.$name;}}class Green implements Color{public function bepaint($penType, $name) {echo $penType.'綠色的'.$name;}}class Blue implements Color{public function bepaint($penType, $name) {echo $penType.'藍色的'.$name;}}class White implements Color{public function bepaint($penType, $name) {echo $penType.'白色的'.$name;}}class Black implements Color{public function bepaint($penType, $name) {echo $penType.'黑色的'.$name;}}

(3)抽象類別Pen

abstract class Pen {protected $color;public function setColor($Color) {$this->color = $Color;}abstract function draw($name);}

(4) 擴充抽象類別

class BigPen extends Pen{public function draw($name) {$penType = '大號鉛筆繪製';$this->color->bepaint($penType,$name);}}class MiddlePen extends Pen{public function draw($name) {$penType = '中號鉛筆繪製';$this->color->bepaint($penType,$name);}}class SmallPen extends Pen{public function draw($name) {$penType = '小號鉛筆繪製';$this->color->bepaint($penType,$name);}}

(5) 輔助代碼

$string = simplexml_load_file('config.xml');foreach ($string as $v) {eval("\$pen = new {$v->type}();");eval("\$color = new {$v->color}();");$pen->setColor($color);$pen->draw("鮮花");echo "
";}

config.xml

            Red    BigPen         Blue    SmallPen         

大號鉛筆繪製紅色的鮮花
小號鉛筆繪製藍色的鮮花
