Are there any specific functions or methods in PHP that can handle PDF file manipulation effectively?

To handle PDF file manipulation effectively in PHP, you can use libraries like TCPDF or FPDF. These libraries provide functions and methods to create, edit, and manipulate PDF files easily. By using these libraries, you can generate PDF files dynamically, add text, images, and other elements to them, and even merge multiple PDF files together. 

// Example using TCPDF library to create a simple PDF file
require_once('tcpdf/tcpdf.php');

// Create new PDF document
$pdf = new TCPDF();

// Set document information
$pdf->SetCreator('Your Name');
$pdf->SetAuthor('Your Name');
$pdf->SetTitle('Sample PDF');
$pdf->SetSubject('Sample PDF using TCPDF');
$pdf->SetKeywords('TCPDF, PDF, example, sample');

// Add a page
$pdf->AddPage();

// Set font
$pdf->SetFont('helvetica', '', 12);

// Add content
$pdf->Cell(0, 10, 'Hello World!', 0, 1, 'C');

// Output PDF to browser
$pdf->Output('sample.pdf', 'I');
