PHP抽奖算法程序代码分享_php实例
抽奖算法需要满足的需求如下:
1.可以控制中奖的概率
2.具有随机性
3.最好可以控制奖品的数量
4.根据用户ID或者ip、手机号、QQ号等条件限制抽奖次数
初期就这些需求,然后根据网上的资料,采用了一种阶段式抽取的方法,大家下面看一下整体的程序:
该程序是在ThinkPHP框架下完成的,使用了一些框架自带的类库和函数,下面我会逐一进行说明,控制器部分:
代码如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 |

该算法简单使用,并发访问性能非常好,稍加改动就可以用于各种场合,结合用户登录等信息可有效控制每个人的抽奖次数。将开始和结束之间更改为数组,就可以完善成为每天特定时间抽奖的程序。
希望大家可以结合有关php抽奖程序的文章进行深入学习,更好的掌握这门语言的应用技巧。
