                        $temp=$genes[$i][$rand0];
                        $genes[$i][$rand0]=0;
                        for($k=$rand0+1;$k<=$num*2+$j;$k++)
                        {
                                $temp1=$genes[$i][$k];
                                $genes[$i][$k]=$temp;
                                $temp=$temp1;
                        }
                }
$num=4
小弟要在阵列中随机插入3个0
插入0后其他数值往后移一格
echo出来阵列中的值都对
只是上面会显示一堆
