My form image 我正在使用具有复选框和选择选项的表单。使用 PHP 导入我的 csv 文件后，它会使用列标题正确显示数据。但是，在如何仅显示带有所选选项的 CHECKED 框时遇到了真正的麻烦。

View image form 如何仅显示选定复选框的选定选项。请帮忙。

尝试用下面的代码替换你完整的 foraeach foreach($_POST['lang'] as $value){...} 部分

foreach ($_POST['lang'] as $key => $value) {

        $method = $package[$key];
        echo "<tr><td>";
        if ($method == 'sum') {
           echo "Sum of " . $value;
        }
        else if ($method == 'mean') {
           echo "mean of " . $value;
        }
        else if ($method == 'mode') {
           echo "mode";
        }
        else {
           echo"no links";
        }
        echo "</td></tr>";
}

希望这能解决这个问题
