How can PHP headers be utilized to ensure proper handling and display of Excel files generated using PHPExcel?

When generating Excel files using PHPExcel, it is important to set the appropriate headers to ensure proper handling and display in the browser. This can be achieved by sending the correct content type and disposition headers before outputting the Excel file content.

header('Content-Disposition: attachment;filename="excel_file.xlsx"');
header('Cache-Control: max-age=0');
