What are the differences between embedding CSS styles directly in HTML files versus linking to external CSS files in PDF generation with PHP?

Embedding CSS styles directly in HTML files can lead to bloated HTML files and can make it harder to maintain and update styles across multiple pages. On the other hand, linking to external CSS files allows for better organization, easier maintenance, and faster loading times. In PDF generation with PHP, it is recommended to link to external CSS files for better code organization and maintainability. 

// Linking to external CSS file in PDF generation with PHP
$html = '<html>
<head>
<link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
<h1>Hello World!</h1>
<p>This is a PDF generated with PHP.</p>
</body>
</html>';

// Generate PDF using TCPDF library
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF();
$pdf->AddPage();
$pdf->writeHTML($html);
$pdf->Output('output.pdf', 'D');
