What are some resources or libraries that can be used in PHP to extract details of a PDF file?

When working with PDF files in PHP, you can use libraries like TCPDF, FPDI, or FPDF to extract details such as text, images, or metadata from a PDF file. These libraries provide functions to parse and manipulate PDF content, allowing you to retrieve specific information from the file. 

// Using TCPDF library to extract text from a PDF file
require_once('tcpdf/tcpdf.php');

// Create new TCPDF object
$pdf = new TCPDF();

// Specify the PDF file to extract text from
$pdfFile = 'example.pdf';

// Open the PDF file
$pdf->setSourceFile($pdfFile);

// Get the total number of pages in the PDF
$totalPages = $pdf->getNumPages();

// Loop through each page and extract text
for ($i = 1; $i <= $totalPages; $i++) {
    $pdf->setPage($i);
    $text = $pdf->getPageText();
    
    // Output the extracted text
    echo $text;
}
