I would like to offer the users of my web application
the ability to export data in the csv format. What I
have come up with currently is writing the stream of
data into a csv file which people can right click and
download.
The downside of this, however, is that the file stays
on the server and theoretically and anybody could find
the URL to the csv file and download it.
Do you know any better way of doing this?
Yes. Have a PHP script pose as a CSV file. Since you
provided no details as to what kind of data you are
going to be exporting, here's a generic example of
exporting data from MySQL:
$query = 'SELECT * FROM my_table';
$result = mysql_query($query)
or die('Query failed: ' . mysql_error());
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename=data.csv');
while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) {
$comma = false;
foreach ($line as $field) {
if (is_numeric($field)) {
$output = $field;
} else {
$output = "'" . str_replace("'", "\\'", $field) . "'";
}
if ($comma) {
$output = ',' . $output;
} else {
$comma = true;
}
echo $output;
}
echo "\r\n";
}
