What are the differences between using FPDF and PDFlib in PHP for creating PDF documents?

FPDF is a free PHP class that allows you to generate PDF files without needing any external libraries. On the other hand, PDFlib is a commercial library that provides more advanced features and support but comes with a cost. If you need basic PDF generation capabilities, FPDF is a good choice. However, if you require more advanced features and are willing to pay for them, PDFlib may be a better option. 

// Example using FPDF to create a simple PDF document
require('fpdf.php');

$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
```

```php
// Example using PDFlib to create a simple PDF document
$p = new PDFlib();
if ($p->begin_document("", "") == 0) {
    die("Error: " . $p->get_errmsg());
}

$p->set_info("Creator", "HelloWorld.php");
$p->set_info("Author", "Rainer Schaaf");
$p->set_info("Title", "Hello world (PHP)!");

$p->begin_page_ext(595, 842, "");

$font = $p->load_font("Helvetica-Bold", "winansi", "");

$p->setfont($font, 24.0);
$p->set_text_pos(50, 700);
$p->show("Hello world!");
$p->end_page_ext("");

$p->end_document("");

print "PDFlib PHP Starter: PDF output done.";
