顯示結果然後給出選項導出到.csv？

Question

我在我的網站上有一個使用PHP和mysql數據庫生成的表格。我想用下面的選項顯示錶格以將結果導出到.csv文件。

我試圖設置一個按鈕/鏈接在底部，將運行下面的PHP文件。 但它只是將整個HTML代碼導出到.csv文件中......有人能幫我解決嗎？

我運行查詢，然後 - >

$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();

通常我創建一個控制器中的新動作下載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`,

      FROM 
       dtb_member

      ORDER BY `day` ASC;" 
      , array($year, $month, $week)); 
      array_push($arrCsvOutputCols,'year','month','week','day'); 
      $title = '"Year","Month","Week","Day",';
