这是我必须编写文件的代码
<?
$date = date(F jS, Y g:i:s a);
$filename = "$date.csv";
$fh = fopen($filename, 'w') or die("can't open file");
$data = "";
fwrite($fh, $data);
fclose($fh);
?>
我需要编写的数据包含mysql查询的输出，如下所示
echo "<tr>";
echo "<td valign='top'>" . nl2br( $row['productid']) . "</td>";
echo "<td valign='top'>" . nl2br( $row['user_id']) . "</td>";

如何将所有这些（上图）纳入$ data，写入我的文件？
答案 0 :(得分：2)
将所有echo替换为$data .=，你应该好好去。 （当然，您需要在之后放置fwrite()和fclose()来电。

$data .= "<td valign='top'>" . nl2br( $row['productid']) . "</td>";
