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.

Accepted Answer

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;
}

header("Content-Type: text/csv");
header("Content-Disposition: attachment; filename=file.csv");

function outputCSV($data) {
  $output = fopen("php://output", "wb");
  foreach ($data as $row)
    fputcsv($output, $row); // here you can change delimiter/enclosure
  fclose($output);
}

outputCSV(array(
  array("name 1", "age 1", "city 1"),
  array("name 2", "age 2", "city 2"),
  array("name 3", "age 3", "city 3")
));

php://output
fputcsv
