What are some common methods for converting PDF pages into images (JPG) using PHP?

To convert PDF pages into images (JPG) using PHP, one common method is to use the Imagick extension, which provides functions for working with images. Another method is to use the Ghostscript command-line tool in conjunction with PHP's exec() function to convert PDF pages into images. Additionally, libraries like TCPDF or FPDI can also be used to extract PDF pages as images. 

// Using Imagick extension
$imagick = new Imagick();
$imagick->setResolution(300, 300);
$imagick->readImage('input.pdf[0]'); // Specify the page number if needed
$imagick->setImageFormat('jpg');
$imagick->writeImage('output.jpg');
$imagick->clear();
$imagick->destroy();

// Using Ghostscript command-line tool
$pdfFile = 'input.pdf';
$outputFile = 'output.jpg';
exec("gs -dSAFER -sDEVICE=jpeg -o $outputFile $pdfFile");

// Using TCPDF
$pdf = new TCPDF();
$pdf->setSourceFile('input.pdf');
$page = $pdf->importPage(1); // Specify the page number if needed
$pdf->AddPage();
$pdf->useTemplate($page);
$pdf->Output('output.jpg', 'F');
