我的网站上有一个使用 PHP 和 mysql DB 生成的表。我想让表格显示下面的选项，以将结果导出到 .csv 文件。

我试图在底部设置一个按钮/链接来运行下面的 php 文件。但是它只是将整个 HTML 代码导出到 .csv 文件中……有人可以帮我吗？

然后我运行查询->

$num_fields = $result->field_count;

$headers = array();

 // Creating headers for output files
for ($i = 0; $i < $num_fields; $i++)
{
    $headers[] = $result->fetch_fields();
}

$fp = fopen('php://output', 'w');
if ($fp && $result)
{
 // name of file with date
    $filename = "AccessReport-".date('Y-m-d').".csv";

        // Setting header types for csv file.
        header('Content-Type: text/csv');
        header('Content-Disposition: attachment; filename='.$filename);
        header('Pragma: no-cache');
        header('Expires: 0');
        fputcsv($fp, $headers);

        while ($row = $result->fetch_assoc())
        {
             fputcsv($fp, $row);
        }

 }
 $result->close();

通常我在控制器中创建一个新动作来下载 CSV，例如

public function csvAction() {

        $year = $this->_getParam('year');
        $month = $this->_getParam('month');
        $week = $this->_getParam('week');

        $arrCsvOutputCols = array();
        $title = '';

        if ($year && $month && $week) {
            $models = $this->db()->fetchAll("
            SELECT 
                YEAR(`create_date`) AS `year`,
                MONTH(`create_date`) AS `month`, 
                WEEK(`create_date`) AS `week`, 
                DAY(`create_date`) AS `day`,
                SUM(case WHEN `age` < 21 then 1 else 0 end) `a`,
                SUM(case WHEN `age` >= 21 AND `age` < 31 then 1 else 0 end) `b`,
