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。

已经很好的解决了。我只是把全部代码放进去，这样新手就能得到全部帮助
<?php
extract($_GET); //you can send some parameter by query variable. I have sent table name in *table* variable
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=$table.csv");
header("Pragma: no-cache");
header("Expires: 0");
require_once("includes/functions.php"); //necessary mysql connection functions here
//first of all I'll get the column name to put title of csv file.
$query = "SHOW columns FROM $table";
$headers = mysql_query($query) or die(mysql_error());
$csv_head = array();
while ($row = mysql_fetch_array($headers, MYSQL_ASSOC))
{
$csv_head[] = $row['Field'];
}
echo implode(",", $csv_head)."\n";
//now I'll bring the data.
$query = "SELECT * FROM $table";
$select_c = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_array($select_c, MYSQL_ASSOC))
{
foreach ($row as $key => $value) {
//there may be separator (here I have used comma) inside data. So need to put double quote around such data.
if(strpos($value, ',') !== false || strpos($value, '"') !== false || strpos($value, "\n") !== false) {
$row[$key] = '"' . str_replace('"', '""', $value) . '"';
}
}
echo implode(",", $row)."\n";
}
?>
我已将此代码保存在csv-download.php中
现在看看我是如何使用这些数据来下载csv文件的
<a href="csv-download.php?table=tbl_vfm"><img title="Download as Excel" src="images/Excel-logo.gif" alt="Download as Excel" /><a/>
因此，当我点击链接，它下载文件，而不带我到浏览器上的csv-download.php页面。

而不是:
$query = "SELECT * FROM customers WHERE created>='{$start} 00:00:00' AND created<='{$end} 23:59:59' ORDER BY id";
$select_c = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_array($select_c, MYSQL_ASSOC))
{
$result.="{$row['email']},";
$result.="\n";
echo $result;
}
Use:
$query = "SELECT * FROM customers WHERE created>='{$start} 00:00:00' AND created<='{$end} 23:59:59' ORDER BY id";
$select_c = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_array($select_c, MYSQL_ASSOC))
{
echo implode(",", $row)."\n";
}

下面是@Andrew发布的php.net函数的改进版本。
function download_csv_results($results, $name = NULL)
{
if( ! $name)
{
$name = md5(uniqid() . microtime(TRUE) . mt_rand()). '.csv';
}
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename='. $name);
header('Pragma: no-cache');
header("Expires: 0");
$outstream = fopen("php://output", "wb");
foreach($results as $result)
{
fputcsv($outstream, $result);
}
fclose($outstream);
}
它真的很容易使用，并且与MySQL(i)/PDO结果集一起工作。
download_csv_results($results, 'your_name_here.csv');
如果完成了页面，请记住在调用此函数后退出()。
要让它以CSV格式发送，并给出文件名，请使用header():
http://us2.php.net/header
header('Content-type: text/csv');
header('Content-disposition: attachment; filename="myfile.csv"');
至于创建CSV本身，您只需要遍历结果集，格式化输出并发送它，就像处理任何其他内容一样。
