In what ways can PHP developers optimize their code for exporting data to Excel to improve efficiency and compatibility with different file formats?

To optimize PHP code for exporting data to Excel, developers can use libraries like PHPExcel or PhpSpreadsheet, which provide a more efficient and compatible way to generate Excel files. These libraries offer features such as support for different file formats, cell styling, and formulas, making it easier to create complex Excel files with PHP. 

// Example using PhpSpreadsheet library to export data to Excel

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');
