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。

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。

<?
// Connect to database
$result = mysql_query("select id
from tablename
where shid=3");
list($DBshid) = mysql_fetch_row($result);
/***********************************
Write date to CSV file
***********************************/
$_file = 'show.csv';
$_fp = @fopen( $_file, 'wb' );
$result = mysql_query("select name,compname,job_title,email_add,phone,url from UserTables where id=3");
while (list( $Username, $Useremail_add, $Userphone, $Userurl) = mysql_fetch_row($result))
{
$_csv_data = $Username.','.$Useremail_add.','.$Userphone.','.$Userurl . "\n";
@fwrite( $_fp, $_csv_data);
}
@fclose( $_fp );
?>
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);
*/
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";
}
除了上述内容，你可能还需要补充:
header("Content-Transfer-Encoding: UTF-8");
它在处理包含多种语言的文件时非常有用，比如人名或城市。
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);
