我在MySQL数据库中有数据。我向用户发送一个URL，以获取他们的数据作为CSV文件。
我有链接的电子邮件，MySQL查询等覆盖。
当他们点击链接时，如何弹出从MySQL下载带有记录的CVS的窗口?
我已经有了所有能拿到唱片的资料。我只是不明白如何让PHP创建CSV文件，并让他们下载一个扩展名为. CSV的文件。

您可以使用fputcsv函数简单地将数据写入CSV。让我们看看下面的例子。将列表数组写入CSV文件
$list[] = array("Cars", "Planes", "Ships");
$list[] = array("Car's2", "Planes2", "Ships2");
//define headers for CSV
header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=file_name.csv');
//write data into CSV
$fp = fopen('php://output', 'wb');
//convert data to UTF-8
fprintf($fp, chr(0xEF).chr(0xBB).chr(0xBF));
foreach ($list as $line) {
fputcsv($fp, $line);
}
fclose($fp);

〇简单的方法
$data = array (
'aaa,bbb,ccc,dddd',
'123,456,789',
'"aaa","bbb"');
$fp = fopen('data.csv', 'wb');
foreach($data as $line){
$val = explode(",",$line);
fputcsv($fp, $val);
}
fclose($fp);
因此$data数组的每一行都将转到新创建的CSV文件的新行。它只适用于PHP 5及以后的版本。
嘿它工作得很好....!!!!谢谢Peter Mortensen和Connor Burton

我知道这个帖子有点老了，但作为将来的参考，以及像我这样的新手:
这里的其他人都解释了如何创建CSV，但忽略了问题的基本部分:如何链接。为了链接到CSV-file的下载，只需链接到.php-file，该文件将响应为. CSV-file。PHP头文件可以做到这一点。这可以实现一些很酷的东西，比如向查询字符串中添加变量并自定义输出:
<a href="my_csv_creator.php?user=23&othervariable=true">Get CSV</a>
my_csv_creator.php可以使用查询字符串中给出的变量，例如使用不同的或自定义的数据库查询，更改CSV的列，个性化文件名等，例如:
User_John_Doe_10_Dec_11.csv
