Are there specific considerations to keep in mind when exporting data to Excel format using PHP?

When exporting data to Excel format using PHP, it is important to ensure that the data is properly formatted and encoded to prevent any issues with special characters. Additionally, the Excel file should be generated with the correct MIME type to prompt the browser to open it in Excel. It is also recommended to set the appropriate headers for the Excel file to ensure proper handling. 

<?php
// Sample data to export to Excel
$data = array(
    array('Name', 'Age', 'Location'),
    array('John Doe', 30, 'New York'),
    array('Jane Smith', 25, 'Los Angeles')
);

// Create a new PHPExcel object
require 'PHPExcel.php';
$objPHPExcel = new PHPExcel();

// Set the active sheet
$objPHPExcel->setActiveSheetIndex(0);

// Add data to the active sheet
foreach ($data as $row => $columns) {
    foreach ($columns as $col => $value) {
        $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row + 1, $value);
    }
}

// Set headers for the Excel file
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="exported_data.xlsx"');
header('Cache-Control: max-age=0');

// Write the Excel file to output
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');
exit;
?>
