$no=0;
            while($bqrf=$empire->fetch($cx)) {
            if($no%1==0){
                $num=1;
             }elseif($no%2==0){
                $num=2;
             }elseif($no%3==0){
                $num=3;
             }
           $no++;
           echo $no;//有值,能循环出来1,2,3,4...................
           echo $num;输出的全是1
上面的$num不能按要求输出,不知为啥


回复讨论(解决方案)

因为全进入 if($no%1==0){ } 这个if了。

 数学啊数学

任何正整数求余1都是0,

 if($no%1==0){                $num=1;
