采用php完全随机设计,每次刷新都有不同幸运号码,试试看,发了财别忘了neo哦~~~

<?php
for ($n = 1; $n <= 5; $n) {
    echo "第" . $n . "注 ";
    $string = ""; //初始化字符串
    for ($i = 1; $i <= 7; $i) {
        mt_srand((double)microtime() * 1000000); //加入时间的因素,以执行时的百万分之一秒当乱数种子
        $random = mt_rand(1, 30); //产生1-30间的随机数
        if (eregi($random, $string)) { //检查此数是否已经存在
            $i--;
            continue; //跳出循环,回到判定起始处。
            
        } else {
            $string = $string . "," . $random;
            echo $random, " ";
        }
    }
    echo "<BR>";
}
