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.

Answer 1

Try:

header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");

echo "record1,record2,record3\n";
die;

etc

Edit: Here's a snippet of code I use to optionally encode CSV fields:

function maybeEncodeCSVField($string) {
    if(strpos($string, ',') !== false || strpos($string, '"') !== false || strpos($string, "\n") !== false) {
        $string = '"' . str_replace('"', '""', $string) . '"';
    }
    return $string;
}
