What are the best practices for exporting data from a MySQL database to an Excel file using PHP?

When exporting data from a MySQL database to an Excel file using PHP, it is best practice to use the PHPExcel library. This library allows for easy creation of Excel files with data fetched from the database. By using this library, you can format the Excel file with headers, styles, and data from the database in a structured manner. 

// Include PHPExcel library
require_once 'PHPExcel/Classes/PHPExcel.php';

// Create new PHPExcel object
$objPHPExcel = new PHPExcel();

// Fetch data from MySQL database
// Example query: $result = mysqli_query($conn, "SELECT * FROM table");
// Loop through results and populate Excel file

// Set headers and styles

// Save Excel file
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('exported_data.xlsx');
