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。

下面是一个使用PDO并包含列标题的完整工作示例:
$query = $pdo->prepare('SELECT * FROM test WHERE id=?');
$query->execute(array($id));
$results = $query->fetchAll(PDO::FETCH_ASSOC);
download_csv_results($results, 'test.csv');
exit();
function download_csv_results($results, $name)
{
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename='. $name);
header('Pragma: no-cache');
header("Expires: 0");
$outstream = fopen("php://output", "wb");
fputcsv($outstream, array_keys($results[0]));
foreach($results as $result)
{
fputcsv($outstream, $result);
}
fclose($outstream);
}

在$output变量中放入CSV数据，并返回正确的报头
header("Content-type: application/download\r\n");
header("Content-disposition: filename=filename.csv\r\n\r\n");
header("Content-Transfer-Encoding: ASCII\r\n");
header("Content-length: ".strlen($output)."\r\n");
echo $output;
首先将data作为String，以逗号作为分隔符(用“，”分隔)。就像这样
$CSV_string="No,Date,Email,Sender Name,Sender Email \n"; //making string, So "\n" is used for newLine
$rand = rand(1,50); //Make a random int number between 1 to 50.
$file ="export/export".$rand.".csv"; //For avoiding cache in the client and on the server
//side it is recommended that the file name be different.
file_put_contents($file,$CSV_string);
/* Or try this code if $CSV_string is an array
fh =fopen($file, 'w');
fputcsv($fh , $CSV_string , "," , "\n" ); // "," is delimiter // "\n" is new line.
fclose($fh);
*/
嘿它工作得很好....!!!!谢谢Peter Mortensen和Connor Burton
<?php
header("Content-type: application/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");
ini_set('display_errors',1);
$private=1;
error_reporting(E_ALL ^ E_NOTICE);
mysql_connect("localhost", "user", "pass") or die(mysql_error());
mysql_select_db("db") or die(mysql_error());
$start = $_GET["start"];
$end = $_GET["end"];
$query = "SELECT * FROM customers WHERE created>='{$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;
}
?>
最简单的方法是使用一个专门的CSV类，像这样:
$csv = new csv();
$csv->load_data(array(
array('name'=>'John', 'age'=>35),
array('name'=>'Adrian', 'age'=>23),
array('name'=>'William', 'age'=>57)
));
$csv->send_file('age.csv');
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。
