Question

如何将相同的随机值27次输入到该数组$ data中？

它输出一个格式正确的表，其中包含一行随机值，现在只需重新设置这些值27次。

数组是二维会让事情变得更难吗？

非常感谢任何和所有帮助我只是一个初学者。

你几乎就在那里..对你的代码做了一些修改，你可以正确地将数据输入到数组中，然后打印出来......我要为修改后的代码添加注释，这样你就可以看到我改变了，为什么。

for($i = 0; $i <= 27; $i++)
{
    $data[] = array($n, $sn, $cwm, $em, $mm, $mr, $com, $stack);
    // There is no need to use $i in the array assignment here, the array inserts already start at zero
    // On top of that, there is no need to have a 3 dimensional array, if you're trying to
    // Get the values to correctly print into a table.
    // Lastly, you can simply add $stack to the array, rather than having to add it on with another line.
}

for ($row = 0; $row < 27; $row++)
{
    echo "<tr>"; // This needs to exist, of course, in order to separate the rows
    for ($col = 0; $col < 7; $col++) //columns output to the number of entries in the array $data
    {
        echo "<td>".$data[$row][$col]."</td>";
        // Otherwise, your code here is fine.
    }
    echo "</tr>"; // see above
}
