PHP幸运大转盘源码，支持ThinkPHP
可以看到1-6等奖都只有1个，7等奖有6个。指针默认指向上图位置，记为0°。 每个奖项对应不同的角度，圆的角度为360°，分成12块，所以每块为30°。 为了防止指针指着相邻两个将向之间的线，所以记为一等奖的最小角度为1°，最大角度为29°。同理可找出其他奖
可以看到1-6等奖都只有1个 ，7等奖有6个。指针默认指向上图位置，记为0°。
每个奖项对应不同的角度，圆的角度为360°，分成12块，所以每块为30°。
为了防止指针指着相邻两个将向之间的线，所以记为一等奖的最小角度为1°，最大角度为29°。同理可找出其他奖项的角度，这要注意，七等奖有6个。
然后呢，每个奖项都有不同的中奖概率，我们根据概率来获取奖项（概率可以设置为0，你懂的～），获取奖品后，在根据最大和最小角度生成一个随机数，来让指针旋转即可..
