纯php实现中秋博饼游戏（2）：掷骰子并输出结果

这篇是纯php实现中秋博饼游戏系列博文（2）

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：

  1 <?php
  2 
  3 class roll
  4 {
  5     private $_defRank = 'lk';
  6 
  7     public function lottery()
  8     {
  9         $dice     = $this->rollDice();
 10         $format   = $this->formatDice($dice);
 11         $rank     = $this->getRank($format);
 12         $rankName = $this->getName($rank);
 13         return [
 14             'dice'     => $dice,
 15             //'format'   => $format,
 16             'rank'     => $rank,
 17             'rankName' => $rankName,
 18         ];
 19     }
 20

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：
