What are the best practices for incorporating interactive elements like zooming and layer selection from OpenLayers into a PDF generated from a PHP webpage?

To incorporate interactive elements like zooming and layer selection from OpenLayers into a PDF generated from a PHP webpage, you can use a library like TCPDF to create a PDF with embedded JavaScript. By including the necessary OpenLayers JavaScript code within the PDF, you can enable interactive features for the map. 

require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('Author');
$pdf->SetTitle('Title');
$pdf->SetSubject('Subject');
$pdf->SetKeywords('Keywords');

$pdf->setPrintHeader(false);
$pdf->setPrintFooter(false);

$pdf->AddPage();

$pdf->Image('map.jpg', 10, 10, 100, '', 'JPG', '', '', true, 150, '', false, false, 0, false, false);

$pdf->IncludeJS("openlayers.js");
$pdf->IncludeJS("map_interactions.js");

$pdf->Output('example.pdf', 'I');
