Output mysql query result to formated excel table with php

Question

I have to fetch the result of a mysql query to a "user friendly" excel (.xls or.xlsx) table. I don't want to use imports or packages for php.

This is what I got so far:

<?php

function query_to_csv($database, $query, $filename, $attachment = false, $headers = true) {

if ($attachment) {
    // send response headers to the browser
    header('Content-Type: text/csv');
    header('Content-Disposition: attachment;filename=' . $filename);
    $fp = fopen('php://output', 'w');
} else {
    $fp = fopen($filename, 'w');
}

$result = mysqli_query($database, $query) or die(mysqli_error($database));
foreach ($result as $fields) {
    fputcsv($fp, $fields);
    
}
    
    fclose($fp);
} 

This is the Result

How can I get the array sperated in different Cells?

Answer 1

Sadly I had to use a library named PHP Excel (old) or PhpSpreadsheet (new).

$objReader->setDelimiter(',');

That's the PHP Excel Function to set the Delimiter.
