I'm following this answer to create a csv file with PHP. But how can I create multiple csv files? Everyone said that those csv files must be sent into zip file. But I don't know how to.
I tried to double the code to make 2 csv files, and then add this at the end, but the zip contains nothing after I downloaded it.

Firstly you will need to create the ZIP folder, create and save each CSV to a temporary location, then add them to the ZIP, delete the temporary CSV file, and finally download the ZIP.
As I don't know what code you're working with exactly here is some code that you should be able to put into your project
// create the ZIP file
$zip_name = 'csv.zip';
$zip = new ZipArchive;
$zip->open($zip_name, ZipArchive::CREATE);
$files = array('file_1.csv', 'file_2.csv', 'file_3.csv');
$temp_directory = 'path to directory';
// create each CSV file and add to the ZIP folder
foreach($files as $file) {
$handle = fopen($temp_directory . $file, 'w');
$data = array(); // data maybe from MySQL to add to your CSV file
// add your data to the CSV file
foreach($data as $d) {
fputcsv($handle, $d);
}
fclose($handle);
// add this file to the ZIP folder
$zip->addFile($temp_directory . $file);
// now delete this CSV file
if(is_file($temp_directory . $file)) {
unlink($temp_directory . $file);
}
}
$zip->close();
