Create a CSV File for a user in PHP

Question

I have data in a MySQL database. I am sending the user a URL to get their data out as a CSV file.

I have the e-mailing of the link, MySQL query, etc. covered.

How can I, when they click the link, have a pop-up to download a CVS with the record from MySQL?

I have all the information to get the record already. I just don't see how to have PHP create the CSV file and let them download a file with a .csv extension.

Hey It works very well....!!!! Thanks Peter Mortensen and 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;
}

?>

You can simply write your data into CSV using fputcsv function. let us have a look at the example below. Write the list array to CSV file

$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);
