How to create formated Excel lists from mySQL database? - php

Question

I use a mySQL database and have to create some lists in Excel format (xlsx). The Excel sheets must be formated. For csv export I use phpExcel (I know, it is obsolete but still working).
Which add on do I need to create formated Excel sheets from my mySQL database. I use php to create the frontend.
Thanks,
Markus

This is just a copy of the function i use. It just launches the function when a specific $_GET isset. The function creates a xlsx file. If you want to export the file as .csv you can just change the file extension and edit text/xlsm to text/csv
$gg = $db->prepare("SELECT * FROM beta_mails ORDER BY created DESC");
$gg->execute();
$ggg = $gg->get_result();
$gg->store_result();
while ($row = $ggg->fetch_assoc()) {
$data[] = $row;
}
function getprelaunchCSV(){
global $data;
header('Content-Type: text/xlsx; charset=utf-8');
header('Content-Disposition: attachment; filename=data.xlsx');
// create a file pointer connected to the output stream
$output = fopen('php://output', 'w');
// output the column headings
fputcsv($output, array('ID', 'EMAIL', 'OPRETTET'));
foreach ($data as $rowCSV){
fputcsv($output, [$rowCSV["id"], decrypt($rowCSV["email"]), $rowCSV["created"]]);
}
fclose($output);
die();
}
if (isset($_GET["getlist"]) && $_GET["getlist"] == "1") {
echo getprelaunchcsv();
header("Location:admin?success=1");
}
