How can the FPDF addon for rotation be properly integrated into a PHP project?

To integrate the FPDF addon for rotation into a PHP project, you need to include the addon file in your project and then use the rotation methods provided by FPDF to rotate elements such as text or images in your PDF document.

// Include the FPDF library and the rotation addon
require('fpdf.php');
require('fpdf_rotate.php');

// Create a new FPDF instance
$pdf = new FPDF();
$pdf->AddPage();

// Rotate the text by 45 degrees
$pdf->Rotate(45);
$pdf->SetFont('Arial', '', 12);
$pdf->Text(50, 50, 'Rotated text');

// Rotate an image by 90 degrees
$pdf->Rotate(90);
$pdf->Image('image.jpg', 100, 100, 50, 50);

// Reset the rotation back to 0 degrees
$pdf->Rotate(0);

// Output the PDF
$pdf->Output();
