在PHPExcel中獲取標題

Question

我在PHP中使用這段代碼來查詢數據庫並將數據導入到excel文件中。目前我正在從數據庫中獲取數據，但我無法獲取標題。

誰能告訴我如何從數據庫中獲取標題？

$objPHPExcel = new PHPExcel(); 

$col = 1; 
while($row_data = mysql_fetch_assoc($result)) { 
    $row = 1; 
    foreach($row_data as $value) { 
     $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value); 
     $row++; 
    } 
    $col++; 
}

$objPHPExcel = new PHPExcel(); 

$col = 1; 
while($row_data = mysql_fetch_assoc($result)) { 
    $row = 1; 
    if ($col == 1) { 
     $row_headings = array_keys($row_data); 
     foreach($row_headings as $value) { 
      $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value); 
      $row++; 
     } 
     $row = 1; 
     $col++; 
    } 
    foreach($row_data as $value) { 
     $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value); 
     $row++; 
    } 
    $col++; 
}
