Are there any best practices for efficiently writing data to PDF or XLS files in PHP?

When writing data to PDF or XLS files in PHP, it is important to use libraries or extensions specifically designed for this purpose, such as TCPDF for PDF files and PHPExcel for XLS files. These libraries provide efficient methods for generating and writing data to the respective file formats, ensuring compatibility and optimal performance. 

// Example using TCPDF for writing data to a PDF file
require_once('tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->SetFont('Arial', '', 12);
$pdf->Cell(0, 10, 'Hello World', 0, 1);
$pdf->Output('example.pdf', 'F');
```

```php
// Example using PHPExcel for writing data to an XLS file
require_once('PHPExcel.php');

$excel = new PHPExcel();
$sheet = $excel->getActiveSheet();
$sheet->setCellValue('A1', 'Hello');
$sheet->setCellValue('B1', 'World');
$writer = PHPExcel_IOFactory::createWriter($excel, 'Excel5');
$writer->save('example.xls');
