How can the code be structured to ensure a smooth redirection process to an Excel file in PHP?

To ensure a smooth redirection process to an Excel file in PHP, you can use the header() function to set the appropriate content type and file name for the Excel file before outputting any data. This will prompt the browser to download the file instead of displaying it in the browser window.

<?php
// Set the appropriate content type and file name for Excel
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment; filename="excel_file.xls"');

// Output Excel data here
echo "Name\tAge\tLocation\n";
echo "John\t25\tNew York\n";
echo "Jane\t30\tLos Angeles\n";
?>
