纯php实现中秋博饼游戏（1）：绘制骰子图案

http://www.cnblogs.com/zqifa/p/php-dice-1.html
要纯php实现，就要用php来生成图案，第一步就先绘制骰子图案。下面就是编码实现业务逻辑，具体代码如下：

 <?php

 class roll
 {
     private $_defRank = 'lk';

     public function lottery()
     {
         $dice     = $this->rollDice();
         $format   = $this->formatDice($dice);
         $rank     = $this->getRank($format);
         $rankName = $this->getName($rank);
         return [
             'dice'     => $dice,
             //'format'   => $format,
             'rank'     => $rank,
             'rankName' => $rankName,
         ];
     }

     /**
      * 获取筛子排名结果
      * @param $dice
      * @return array
      */
     public function getRes($dice)
     {
         $format   = $this->formatDice($dice);
         $rank     = $this->getRank($format);
         $rankName = $this->getName($rank);
         return [
             'dice'     => $dice,
             'format'   => $format,
             'rank'     => $rank,
             'rankName' => $rankName,
         ];
     }

     /**
      * 掷骰子
      * @return array
      */
     public function rollDice()
     {
         $res = [];
         for ($i = 0; $i < 6; $i++) {
             $res[] = mt_rand(1, 6);
         }
         return $res;
     }

     /**

             4 => 0,
             5 => 0,
             6 => 0,
         ];
         foreach ($list as $val) {
             if (isset($data[$val])) {
                 $data[$val] += 1;
             }
         }

             if ($val == 0) {

             }
         }
         return $data;
     }

     /**

                 }
                 //有一条规则匹配，跳出循环，

         ];
     }
 }

 $roll = new roll();
 $res = $roll->lottery();

 echo '<h2>骰子点数：</h2>';
 echo '<p>';
 foreach($res['dice'] as $val){
     echo '<img src="img.php?num='.$val.'" >';
 }
 echo '</p>';

 echo '<h2>结果：</h2>';
 echo '<h2 style="color:red;">'.$res['rankName'].'</h2>';

其中img.php是使用php生成图片的文件，参数num是点数，然后输出相应点数的图片，代码如下：

 <?php

 class imgDock
 {
     public function getImg($num = 0)
     {
         if(!empty($num)){
             header('Content-Type:image/png');
             $img   = imagecreatetruecolor(200, 200);
             $white = imagecolorallocate($img, 255, 255, 255);
             $grey  = imagecolorallocate($img, 100, 100, 100);
             $blue  = imagecolorallocate($img, 0, 102, 255);
             $red   = imagecolorallocate($img, 255, 0, 0);
             imagefill($img, 0, 0, $white);
             imageline($img, 10, 20, 10, 180, $grey);
             imageline($img, 10, 180, 20, 190, $grey);
             imageline($img, 20, 190, 180, 190, $grey);
             imageline($img, 180, 190, 190, 180, $grey);
             imageline($img, 190, 180, 190, 20, $grey);
             imageline($img, 190, 20, 180, 10, $grey);
             imageline($img, 180, 10, 20, 10, $grey);
             imageline($img, 20, 10, 10, 20, $grey);

             //1/2/3/4/5/6
             switch($num){
