Are there any known compatibility issues when using PHP functions to create Excel files, especially when targeting Excel 2000 to present versions?

When using PHP functions to create Excel files, there can be compatibility issues when targeting older versions of Excel, such as Excel 2000. To ensure compatibility with all versions of Excel, it is recommended to use the PHPExcel library, which provides a more robust and reliable solution for creating Excel files. 

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

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

// Set properties for Excel file
$objPHPExcel->getProperties()->setCreator("Your Name")
                             ->setLastModifiedBy("Your Name")
                             ->setTitle("Title")
                             ->setSubject("Subject")
                             ->setDescription("Description");

// Add data to Excel file
$objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A1', 'Hello')
            ->setCellValue('B1', 'World');

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