Are there any best practices for efficiently creating and saving XLSX files from PHP scripts?

When creating and saving XLSX files from PHP scripts, it is recommended to use a library like PHPSpreadsheet for efficient handling of Excel files. This library allows you to easily create and manipulate Excel files in XLSX format. To use PHPSpreadsheet, you need to install it via Composer and then use its classes and methods to create and save XLSX files. 

// Include the Composer autoloader
require 'vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

// Create a new Spreadsheet object
$spreadsheet = new Spreadsheet();

// Add data to the spreadsheet
$sheet = $spreadsheet->getActiveSheet();
$sheet->setCellValue('A1', 'Hello');
$sheet->setCellValue('B1', 'World');

// Save the spreadsheet to a file
$writer = new Xlsx($spreadsheet);
$writer->save('hello_world.xlsx');
