我的网站上有一个表，它使用PHP和mysql DB生成。我想让表格显示下面的选项，将结果导出到.csv文件。
我试图在底部设置一个按钮/链接，运行下面的php文件。 然而，它只是将整个HTML代码导出到.csv文件中...有人可以帮助我吗？
然后我运行查询 - ＆gt;
$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();
答案 0 :(得分：0)
通常我在控制器中创建一个新动作以下载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`,

array_push($arrCsvOutputCols,'year','month','week','day');
