php扔骰子举例

为6再扔一次，若不为6，前进扔出步数

<?php    //while例子$sum  = 0; $num = rand(1,6); //获取1至6的随机数，模拟掷骰子$sum = $sum  + $num;//前进步长while($num==6){$num = rand(1,6);//获取1至6的随机数，模拟掷骰子$sum = $sum  + $num;//前进步长};echo "while例子执行完毕，前进：".$sum ."<br />";//do...while例子$sum  = 0; do{$num = rand(1,6);//获取1至6的随机数，模拟掷骰子$sum = $sum  + $num;//前进步长}while($num==6);echo "do...while例子执行完毕，前进：".$sum ."<br />";?>
